|

* Comments are any lines whose first non-whitespace character is ';' or '#'.
|

* Note that comments can also follow a value, on the same line.
|
||||
* To intentionally have a '#' character in the value, use ##
|
||||
*
|
||||
* All parameters fall into sections. To name a section, the first
|
||||
* non-whitespace character on the line will be '[', and the last will be ']'.
|
||||
*
|
||||
* Parameters are simple key=value pairs. Whitespace around the '=', and at the
|
||||
* beginning or end of the line is ignored. Key names may not contain '=' nor
|
||||
* begin with '[', however values can. If the last character of the value is
|
||||
* '\', the next line (sans leading/trailing whitespace) is considered part of
|
||||
* the value as well. Programmatically, the key "K" in section "S" is referred
|
||||
* to as "S::K", much like C++ namespaces. For example:
|
||||
* [Section1]
|
||||
* # this is a comment

* foo = bar \
|
||||
* baz\
|
||||
* quux \
|
||||
* ## this is not a comment! # this IS a comment
|
||||
* means the value of "Section1::foo" is "bar bazquux # this is not a comment!"
|
||||
*
|
||||
* Parameters may be of several types:
|
||||
* String - Bare characters. If the first and last characters are both '"',
|
||||
* they are removed (so just double them if you really want quotes
|
||||
* there)
|
||||
* Int - A decimal number from -2147483648 to 2147483647
|
||||
* UInt - A number in decimal, hex, or octal from 0 to 4294967295 (or
|
||||
* 0xffffffff, or 037777777777)
|
||||
* Bool - true/false, 0/1, on/off, yes/no
|
||||
*
|
||||
* Of course, the actual accepted values for a parameter may be further
|
||||
* restricted ;)

## - A two-digit number (i.e. with leading zeros)
|

This lists the available commands, excluding the ones you get back from
|
||||
S9xGetAllSnes9xCommands(). The various meta-characters are:
|
||||
# - A number. The range is determined by the context
|
||||
## - A two-digit number (i.e. with leading zeros)
|
||||
[...] - Something optional
|
||||
(...) - For grouping with |
|
||||
| - "or", choose one of the options.
|
||||
<...> - A named field
|
||||
{...} - A list of possible values. Multiple values may be used, but they
|
||||
must be in the order listed and joined with +-signs.
|
||||
"" - 'ditto', used to indicate the same list as the above line.
|
||||
|
||||
Speeds are: Var, Slow, Med, and Fast. 'Var' starts slow and speeds up as the
|
||||
button is held.
|
||||
|
||||
Axes are: Left/Right, Right/Left, Up/Down, Down/Up, Y/A, A/Y, X/B, B/X, L/R,
|
||||
and R/L. Negative is listed first (i.e. "Y/A" means negative deflection is
|
||||
towards Y, while "A/Y" means negative deflection is towards A).
|
||||
|
||||
AxisToPointer, ButtonToPointer, and AxisToButtons allow for translating
|
||||
between different input types. There are 8 'pointers' with IDs
|
||||
PseudoPointerBase+0 to PseudoPointerBase+7, and 256 'buttons' with IDs
|
||||
PseudoButtonBase+0 to PseudoButtonBase+255. So for example,
|
||||
"AxisToButtons 0/255 T=50%" would take the axis data, and do
|
||||
S9xReportButton(PseudoButtonBase+0,1) when said axis goes past 50% in the
|
||||
negative direction and S9xReportButton(PseudoButtonBase+255,1) when it goes
|
||||
over 50% deflection in the positive direction. Similarly, it will do
|
||||
S9xReportButton(...,0) when the deflection drops under 50% in either
|
||||
direction. "ButtonToPointer 1u Slow" would move the pointer with ID
|
||||
PseudoPointerBase+0 up one pixel per frame as long as the button is pressed
|
||||
(reporting this change at the end of each frame).

Multis
|
||||
------
|
||||
|
||||
Multis are a type of button command. The basic format of a multi is "{...}",
|
||||
where the '...' consists of 1 or more valid non-multi button command
|
||||
strings. The braces are literal, not metacharacters. Subcommands separated
|
||||
by commas are executed one after the next. Semicolons skip one frame before
|
||||
continuing subcommand execution. Semicolons may be repeated. When the multi
|
||||
button is pressed, each subcommand is 'pressed', and when the multi button
|
||||
is released each subcommand is 'released'.
|
||||
|
||||
There are also press-only multis, defined as "+{...}". These act just like
|
||||
regular multis, with two differences: the multi is only run when you press
|
||||
the button (release is ignored), and each subcommand must be prefixed with
|
||||
'+' or '-' to indicate whether the the subcommand should be pressed or
|
||||
released.
|
||||
|
||||
For example: {Joypad1 A,Joypad2 A;Joypad3 A;;;;;QuickSave000}
|
||||
This presses (or releases) A on pads 1 and 2, then waits one frame, then
|
||||
presses A on pad 3, then waits 5 frames, then saves to snapshot 0 (on press
|
||||
only).
|
||||
|
||||
You may access the multi number in the returned s9xcommand_t structure as
|
||||
cmd.button.multi_idx. This may be used to assign the same multi to multiple
|
||||
buttons:
|
||||
MULTI#<num> ; NOTE: that's a literal octothorpe

</div>
|
||||
<h2>Introduction</h2>
|
||||
<p>
|
||||
This is brief description of the steps to port Snes9x to the new platform. It describes what code you have to write and what functions exist that you can make use of. It also gives some insights as to how Snes9x actually works, although that will be subject of another document yet to be written.
|
||||
</p>
|
||||
<h2>System Requirements</h2>
|
||||
<p>
|
||||
A C++ compiler. For the most part Snes9x really isn't written in C++, it just uses the C++ compiler as a “better C” compiler to get inline functions and so on. GCC is good for compiling Snes9x (<a href="http://gcc.gnu.org/">http://gcc.gnu.org/</a>).
|
||||
</p>
|
||||
<p>
|
||||
A fast CPU. SNES emulation is very compute intensive; two, or sometimes three CPUs to emulate, an 8-channel 16-bit stereo sound digital signal processor with real-time sample decompression, filter and echo effects, two custom graphics processor chips that can produce transparency, scaling, rotation and window effects in 32768 colors, and finally hardware DMA all take their toll on the host CPU.
|
||||
</p>
|
||||
<p>
|
||||
Enough RAM. Snes9x uses 8MB to load SNES ROM images and several MB for emulating sound, graphics, custom chips, and so on.
|
||||
</p>
|
||||
<p>
|
||||
A 16-bit color (two bytes per pixel) or deeper display, at least 512*478 pixels in resolution. Pixel format conversion may be required before you place the rendered SNES screen on to the display.
|
||||
</p>
|
||||
<p>
|
||||
Snes9x outputs 16-bit stereo digital sound data. Ports may convert it from there to 8-bit or mono. Some ports can use interrupts or callbacks from the sound system to know when more sound data is required, most other ports have to periodically poll the host sound system to see if more data is required; if it is then the sound mixing code is called to fill the sound buffer with SNES sound data, which then can be passed on to the host sound system. Sound data is generated as an array of bytes (<code>uint8</code>) for 8-bit sound or shorts (<code>int16</code>) for 16-bit data. Stereo sound data generates twice as many samples, with each channel's samples interleaved, first left's then right's.
|
||||
</p>
|
||||
<p>
|
||||
For the user to be able to control and play SNES games, some form of input device is required, a joypad or keyboard, for example. The real SNES can have 2 eight-button digital joypads connected to it or 5 joypads when an optional multi-player adaptor is connected, although most games only require a single joypad. Access to all eight buttons and the direction pad, of course, are usually required by most games. Snes9x does emulate the multi-player adaptor hardware, if you were wondering, but its still up to you to provide the emulation of the individual joypads.
|
||||
</p>
|
||||
<p>
|
||||
The real SNES also has a SNES mouse, Super Scope and Justifier (light-gun) available as optional extras. Snes9x can emulate all of these using some form of pointing device, usually the host system's mouse.
|
||||
</p>
|
||||
<p>
|
||||
Some SNES game cartridges contains a small amount of extra RAM and a battery, so ROMs could save a player's progress through a game for games that takes many hours to play from start to finish. Snes9x simulates this S-RAM by saving the contents of the area of memory occupied by the S-RAM into a file then automatically restoring it again the next time the user plays the same game. If the hardware you're porting to doesn't have a storage media available then you could be in trouble.
|
||||
</p>
|
||||
<p>
|
||||
Snes9x also implements freeze-game files which can record the state of the SNES hardware and RAM at a particular point in time and can restore it to that exact state at a later date - the result is that users can save a game at any point, not just at save-game or password points provided by the original game coders. Each freeze file is over 400k in size. To help save disk space, Snes9x can be compiled with zlib (<a href="http://www.zlib.net/">http://www.zlib.net/</a>), which is used to GZIP compress the freeze files, reducing the size to typically below 100k. zlib is also used to load GZIP or ZIP compressed ROM images. Additionally, Snes9x supports JMA archives compressed with NSRT (<a href="http://nsrt.edgeemu.com/">http://nsrt.edgeemu.com/</a>).
|
||||
</p>
|
||||
<h2>Compile-Time Options</h2>
|
||||
<h3><code>DEBUGGER</code></h3>
|
||||
<p>
|
||||
Enables extra code to assist you in debugging SNES ROMs. The debugger has only ever been a quick-hack and user-interface to debugger facilities is virtually non-existent. Most of the debugger information is output via stdout and enabling the debugger slows the whole emulator down slightly. However, the debugger options available are very powerful; you could use it to help get your port working. You probably still want to ship the finished version with the debugger disabled, it will only confuse non-technical users.
|
||||
</p>
|
||||
<h3><code>RIGHTSHIFT_IS_SAR</code></h3>
|
||||
<p>
|
||||
Define this if your compiler uses shift right arithmetic for signed values. For example, GCC and Visual C++ use shift right arithmetic.
|
||||
</p>
|
||||
<h3><code>ZLIB / UNZIP_SUPPORT / JMA_SUPPORT</code></h3>
|
||||
<p>
|
||||
Define these if you want to support GZIP/ZIP/JMA compressed ROM images and GZIP compressed freeze-game files.
|
||||
</p>
|
||||
<h3><code>USE_OPENGL</code></h3>
|
||||
<p>
|
||||
Define this and set <code>Settings.OpenGLEnable</code> to <code>true</code>, then you'll get the rendered SNES image as one OpenGL texture.
|
||||
</p>
|
||||
<h3>Typical Options Common for Most Platforms</h3>
|
||||
<p><code>
|
||||
ZLIB<br>
|
||||
UNZIP_SUPPORT<br>
|
||||
JMA_SUPPORT<br>
|
||||
RIGHTSHIFT_IS_SAR<br>
|
||||
</code></p>
|
||||
<h2>Editing port.h</h2>
|
||||
<p>
|
||||
You may need to edit <code>port.h</code> to fit Snes9x to your system.
|
||||
</p>
|
||||
<p>
|
||||
If the byte ordering of your system is least significant byte first, make sure <code>LSB_FIRST</code> is defined, otherwise make sure it's not defined.
|
||||
</p>
|
||||
<p>
|
||||
You'll need to make sure what pixel format your system uses for 16-bit colors (<code>RGB565</code>, <code>RGB555</code>, <code>BGR565</code> or <code>BGR555</code>), and if it's not <code>RGB565</code>, define <code>PIXEL_FORMAT</code> to it so that Snes9x will use it to render the SNES screen. For example, Windows uses <code>RGB565</code>, Mac OS X uses <code>RGB555</code>. If your system supports more than one pixel format, you can define <code>GFX_MULTI_FORMAT</code> and change Snes9x's pixel format dynamically by calling <code>S9xSetRenderPixelFormat</code> function. If your system is 24 or 32-bit only, then don't define anything; instead write a conversion routine that will take a complete rendered 16-bit SNES screen in <code>RGB565</code> format and convert to the format required to be displayed on your system.
|
||||
</p>
|
||||
<p>
|
||||
<code>port.h</code> also typedefs some types; <code>uint8</code> for an unsigned 8-bit quantity, <code>uint16</code> for an unsigned 16-bit quantity, <code>uint32</code> for a 32-bit unsigned quantity and <code>bool8</code> for a <code>true</code>/<code>false</code> type. Signed versions are also typedef'ed.
|
||||
</p>
|
||||
<h2>Controllers Management</h2>
|
||||
<p>
|
||||
Read <code>controls.h</code>, <code>crosshair.h</code>, <code>controls.txt</code> and <code>control-inputs.txt</code> for details. This section is the minimal explanation to get the SNES controls workable.
|
||||
</p>
|
||||
<p>
|
||||
The real SNES allows several different types of devices to be plugged into the game controller ports. The devices Snes9x emulates are a joypad, multi-player adaptor known as the Multi Player 5 or Multi Tap (allowing a further 4 joypads to be plugged in), a 2-button mouse, a light gun known as the Super Scope, and a light gun known as the Justifier.
|
||||
</p>
|
||||
<p>
|
||||
In your initialization code, call <code>S9xUnmapAllControl</code> function.
|
||||
</p>
|
||||
<p>
|
||||
Map any IDs to each SNES controller's buttons and pointers. (ID 249-255 are reserved).
|
||||
</p>
|
||||
<p>
|
||||
Typically, use <code>S9xMapPointer</code> function for the pointer of the SNES mouse, Super Scope and Justifier, <code>S9xMapButton</code> function for other buttons. Set <code>poll</code> to <code>false</code> for the joypad buttons, <code>true</code> for the other buttons and pointers.
|
||||
</p>
|
||||
<p>
|
||||
<code>S9xMapButton(k1P_A_Button, s9xcommand_t cmd = S9xGetCommandT("Joypad1 A"), false);</code>
|
||||
</p>
|
||||
<p>
|
||||
In your main emulation loop, before <code>S9xMainLoop</code> function is called, check your system's keyboard/joypad, and call <code>S9xReportButton</code> function to report the states of the SNES joypad buttons to Snes9x. Checking and reporting input immediately before <code>S9xMainLoop</code> is preferred to minimize input latency.
|
||||
</p>
|
||||
<p>
|
||||
<code>void MyMainLoop (void)<br>
|
||||
{<br>
|
||||
MyReportButttons();<br>
|
||||
S9xMainLoop();<br>
|
||||
}</code>
|
||||
</p>
|
||||
<p>
|
||||
<code>void MyReportButtons (void)<br>
|
||||
{<br>
|
||||
S9xReportButton(k1P_A_Button, (key_is_pressed ? true : false));<br>
|
||||
}</code>
|
||||
</p>
|
||||
<p>
|
||||
Prepare your <code>S9xPollButton</code> and <code>S9xPollPointer</code> function to reply Snes9x's request for other buttons/cursors states.
|
||||
</p>
|
||||
<p>
|
||||
Call <code>S9xSetController</code> function. It connects each input device to each SNES input port.<br>
|
||||
Here's typical controller settings that is used by the real SNES games:
|
||||
</p>
|
||||
<p>Joypad<br>
|
||||
<code>S9xSetController(0, CTL_JOYPAD, 0, 0, 0, 0);<br>
|
||||
S9xSetController(1, CTL_JOYPAD, 1, 0, 0, 0);</code>
|
||||
</p>
|
||||
<p>Mouse (port 1)<br>
|
||||
<code>S9xSetController(0, CTL_MOUSE, 0, 0, 0, 0);<br>
|
||||
S9xSetController(1, CTL_JOYPAD, 1, 0, 0, 0);</code>
|
||||
</p>
|
||||
<p>Mouse (port 2)<br>
|
||||
<code>S9xSetController(0, CTL_JOYPAD, 0, 0, 0, 0);<br>
|
||||
S9xSetController(1, CTL_MOUSE, 1, 0, 0, 0);</code>
|
||||
</p>
|
||||
<p>Super Scope<br>
|
||||
<code>S9xSetController(0, CTL_JOYPAD, 0, 0, 0, 0);<br>
|
||||
S9xSetController(1, CTL_SUPERSCOPE, 0, 0, 0, 0);</code>
|
||||
</p>
|
||||
<p>Multi Player 5<br>
|
||||
<code>S9xSetController(0, CTL_JOYPAD, 0, 0, 0, 0);<br>
|
||||
S9xSetController(1, CTL_MP5, 1, 2, 3, 4);</code>
|
||||
</p>
|
||||
<p>Justifier<br>
|
||||
<code>S9xSetController(0, CTL_JOYPAD, 0, 0, 0, 0);<br>
|
||||
S9xSetController(1, CTL_JUSTIFIER, 0, 0, 0, 0);</code>
|
||||
</p>
|
||||
<p>Justifier (2 players)<br>
|
||||
<code>S9xSetController(0, CTL_JOYPAD, 0, 0, 0, 0);<br>
|
||||
S9xSetController(1, CTL_JUSTIFIER, 1, 0, 0, 0);</code>
|
||||
</p>
|

<h2>Existing Interface Functions</h2>
|
||||
<h3><code>bool8 Memory.Init (void)</code></h3>
|
||||
<p>
|
||||
Allocates and initializes several major lumps of memory, for example the SNES ROM and RAM arrays, tile cache arrays, etc. Returns <code>false</code> if memory allocation fails.
|
||||
</p>
|
||||
<h3><code>void Memory.Deinit (void)</code></h3>
|
||||
<p>
|
||||
Deallocates the memory allocations made by <code>Memory.Init</code> function.
|
||||
</p>
|
||||
<h3><code>bool8 S9xGraphicsInit (void)</code></h3>
|
||||
<p>
|
||||
Allocates and initializes several lookup tables used to speed up SNES graphics rendering. Call after you have initialized the <code>GFX.Screen</code> and <code>GFX.Pitch</code> values. Returns <code>false</code> if memory allocation fails.
|
||||
</p>
|
||||
<h3><code>void S9xGraphicsDeinit (void)</code></h3>
|
||||
<p>
|
||||
Deallocates the memory allocations made by <code>S9xGraphicsInit</code> function.
|
||||
</p>
|
||||
<h3><code>bool8 S9xInitAPU (void)</code></h3>
|
||||
<p>
|
||||
Allocates and initializes several arrays used by the sound CPU and sound generation code. Returns <code>false</code> if memory allocation fails.
|
||||
</p>
|
||||
<h3><code>void S9xDeinitAPU (void)</code></h3>
|
||||
<p>
|
||||
Deallocates the allocations made by <code>S9xInitAPU</code> function.
|
||||
</p>
|
||||
<h3><code>bool8 S9xInitSound (int buffer_ms)</code></h3>
|
||||
<p>
|
||||
Allocates memory for mixing and queueing SNES sound data, does more sound code initialization and opens the host system's sound device by calling <code>S9xOpenSoundDevice</code>, a function you must provide. Before calling this function you must set up <code>Settings.SoundSync</code>, <code>Settings.SoundPlaybackRate</code>, and <code>Settings.SoundInputRate</code>. (see section below)<br>
|
||||
<code>buffer_ms</code>, given in milliseconds, is the memory buffer size for queueing sound data. Leave this at 0 to use the suggested default.<br>
|
||||
</p>
|
||||
<h3><code>void S9xReset (void)</code></h3>
|
||||
<p>
|
||||
Resets the SNES emulated hardware back to the state it was in at “switch-on” except the S-RAM area is preserved (“hardware reset”). The effect is it resets the current game back to the start. This function is automatically called by <code>Memory.LoadROM</code> function.
|
||||
</p>
|
||||
<h3><code>void S9xSoftReset (void)</code></h3>
|
||||
<p>
|
||||
Similar to <code>S9xReset</code> function, but “software reset” as you press the SNES reset button.
|
||||
</p>
|
||||
<h3><code>bool8 Memory.LoadROM (const char *filepath)</code></h3>
|
||||
<p>
|
||||
Attempts to load the specified ROM image filename into the emulated ROM area. There are many different SNES ROM image formats and the code attempts to auto-detect as many different types as it can and in a vast majority of the cases gets it right.<br>
|
||||
There are several ROM image options in the <code>Settings</code>structure; allow the user to set them before calling <code>Memory.LoadROM</code> function, or make sure they are all reset to default values before each call to <code>Memory.LoadROM</code> function. See <code>Settings.ForceXXX</code> in <code>snes9x.h</code>.
|
||||
</p>
|
||||
<h3><code>bool8 Memory.LoadMultiCart (const char *cartApath, const char *cartBpath)</code></h3>
|
||||
<p>
|
||||
Attempts to load multiple ROM images into the emulated ROM area, for the multiple cartridge systems such as Sufami Turbo, Same Game, etc.
|
||||
</p>
|
||||
<h3><code>bool8 Memory.LoadSRAM (const char *filepath)</code></h3>
|
||||
<p>
|
||||
Call this function to load the associated S-RAM save file (if any). The filename should be based on the ROM image name to allow easy linkage. The current ports change the directory and the filename extension of the ROM filename to derive the S-RAM filename.
|
||||
</p>
|
||||
<h3><code>bool8 Memory.SaveSRAM (const char *filepath)</code></h3>
|
||||
<p>
|
||||
Call this function to save the emulated S-RAM area into a file so it can be restored again the next time the user wants to play the game. Remember to call this when just before the emulator exits or when the user has been playing a game and is about to load another one.
|
||||
</p>
|
||||
<h3><code>void S9xMainLoop (void)</code></h3>
|
||||
<p>
|
||||
The emulator main loop. Call this from your own main loop that calls this function (if a ROM image is loaded and the game is not paused), processes any pending host system events, then goes back around the loop again until the emulator exits. <code>S9xMainLoop</code> function normally returns control to your main loop once every emulated frame, when it reaches the start of scan-line zero. However it may take a few frames when a huge memory transfer is being emulated. The function can return more often if the <code>DEBUGGER</code> compile-time flag is defined and the CPU has hit a break point, or the <code>DEBUG_MODE_FLAG</code> bit is set in <code>CPU.Flags</code> or instruction single-stepping is enabled.
|
||||
</p>
|
||||
<h3><code>void S9xMixSamples (uint8 *buffer, int sample_count)</code></h3>
|
||||
<p>
|
||||
Call this function from your host sound system handling code to fill <code>buffer</code> with ready-mixed SNES sound data. The buffer will be filled with an array of <code>sample_count</code> <code>int16</code>. Samples are in pairs, first a left channel sample followed by the right channel sample.<br>
|
||||
If there are fewer queued samples than you request by <code>sample_count</code>, the function fills <code>buffer</code> with silent sound data and returns <code>false</code>.
|
||||
</p>
|
||||
<h3><code>int S9xGetSampleCount (void)</code></h3>
|
||||
<p>
|
||||
Returns the number of sound samples available in the buffer for your configured playback settings.
|
||||
</p>
|
||||
<h3><code>void S9xSetSamplesAvailableCallback (void (*) samples_available (void *), void *data)</code></h3>
|
||||
<p>
|
||||
Call this function to set up a callback that is run when sound samples are made available. <code>samples_available</code> is a function you provide that returns <code>void</code> and takes a pointer as an argument. <code>data</code> is a pointer that you may wish to pass to your callback or can be <code>NULL</code>. Inside this function is the only time that it is safe to access Snes9x's sound data. Ideally, all samples reported available will be removed from Snes9x's buffer when this function is called and moved to either the sound driver output or a separate buffer that can be locked in a thread-safe fashion. If you are using a callback-oriented sound API, it is recommended to set up a separate buffer that can accumulate at least enough samples to fulfill more than one host sound driver callback request.<br>
|
||||
If you wish to disable a callback you have set up or need to temporarily shut down your sound system, you may pass <code>NULL</code> for both arguments.
|
||||
</p>
|
||||
<h3><code>bool8 S9xSyncSound (void)</code></h3>
|
||||
<p>
|
||||
Call this function to synchronize the sound buffers to the game state. This will call the <code>samples_available</code> function to try and move sound data out of Snes9x. If Snes9x is unable to make enough space to accumulate the sound data for a whole video frame, this function will return <code>false</code>. In this case, you may wish to wait until your host sound system uses the available samples, and <code>S9xSyncSound</code> returns <code>true</code> before continuing to execute <code>S9xMainLoop</code>.
|
||||
</p>
|
||||
<h3><code>bool8 S9xSetSoundMute (bool8 mute)</code></h3>
|
||||
<p>
|
||||
Call with a <code>true</code> parameter to cause the <code>S9xMixSamples</code> to fill the output buffer with silence, instead of filling the output buffer with sound data. Useful if your sound system is interrupt or callback driven and the game has been paused either directly or indirectly because the user is interacting with the emulator's user interface in some way.
|
||||
</p>
|
||||
<h3><code>bool8 S9xFreezeGame (const char *filepath)</code></h3>
|
||||
<p>
|
||||
Call this function to record the current SNES hardware state into a file, the file can be loaded back using <code>S9xUnfreezeGame</code> function at a later date effectively restoring the current game to exact same spot. Call this function while you're processing any pending system events when <code>S9xMainLoop</code> function has returned control to you in your main loop.
|
||||
</p>
|
||||
<h3><code>bool8 S9xUnfreezeGame (const char *filepath)</code></h3>
|
||||
<p>
|
||||
Restore the SNES hardware back to the exactly the state it was in when <code>S9xFreezeGame</code> function was used to generate the file specified. You have to arrange the correct ROM is already loaded using <code>Memory.LoadROM</code> function, an easy way to arrange this is to base freeze-game filenames on the ROM image name. The UNIX/Linux ports load freeze-game files when the user presses a function key, with the names romfilename.000 for F1, romfilename.001 for F2, etc. Games are frozen in the first place when the user presses Shift-function key. You could choose some other scheme.
|
||||
</p>
|
||||
<h3><code>void S9xDumpSPCSnapshot (void)</code></h3>
|
||||
<p>
|
||||
Call this funtion to make a so-called SPC file, a snapshot of SNES sound state. Actual dump occurs at the first key-on event after this function is called.
|
||||
</p>
|
||||
<h3><code>void S9xSetInfoString (const char *string)</code></h3>
|
||||
<p>
|
||||
Call this function if you want to show a message onto the SNES screen.
|
||||
</p>
|
||||
<h3>Other Available Functions</h3>
|
||||
<p>
|
||||
See <code>movie.h</code> and <code>movie.cpp</code> to support the Snes9x movie feature.<br>
|
||||
See <code>cheats.h</code>, <code>cheats.cpp</code> and <code>cheats2.cpp</code> to support the cheat feature.
|
||||
</p>
|
||||
<h2>Interface Functions You Need to Implement</h2>
|
||||
<h3><code>bool8 S9xOpenSnapshotFile (const char *filepath, bool8 read_only, STREAM *file)</code></h3>
|
||||
<p>
|
||||
This function opens a freeze-game file. <code>STREAM</code> is defined as a <code>gzFile</code> if <code>ZLIB</code> is defined else it's defined as <code>FILE *</code>. The <code>read_only</code> parameter is set to <code>true</code> when reading a freeze-game file and <code>false</code> when writing a freeze-game file. Open the file <code>filepath</code> and return its pointer <code>file</code>.
|
||||
</p>
|
||||
<h3><code>void S9xCloseSnapshotFile (STREAM file)</code></h3>
|
||||
<p>
|
||||
This function closes the freeze-game file opened by <code>S9xOpenSnapshotFile</code> function.
|
||||
</p>
|
||||
<h3><code>void S9xExit (void)</code></h3>
|
||||
<p>
|
||||
Called when some fatal error situation arises or when the “q” debugger command is used.
|
||||
</p>
|
||||
<h3><code>bool8 S9xInitUpdate (void)</code></h3>
|
||||
<p>
|
||||
Called just before Snes9x begins to render an SNES screen. Use this function if you should prepare before drawing, otherwise let it empty.
|
||||
</p>
|
||||
<h3><code>bool8 S9xDeinitUpdate (int width, int height)</code></h3>
|
||||
<p>
|
||||
Called once a complete SNES screen has been rendered into the <code>GFX.Screen</code> memory buffer, now is your chance to copy the SNES rendered screen to the host computer's screen memory. The problem is that you have to cope with different sized SNES rendered screens: 256*224, 256*239, 512*224, 512*239, 512*448 and 512*478.
|
||||
</p>
|
||||
<h3><code>void S9xMessage (int type, int number, const char *message)</code></h3>
|
||||
<p>
|
||||
When Snes9x wants to display an error, information or warning message, it calls this function. Check in <code>messages.h</code> for the types and individual message numbers that Snes9x currently passes as parameters.<br>
|
||||
The idea is display the message string so the user can see it, but you choose not to display anything at all, or change the message based on the message number or message type.<br>
|
||||
Eventually all debug output will also go via this function, trace information already does.
|
||||
</p>
|
||||
<h3><code>bool8 S9xOpenSoundDevice (void)</code></h3>
|
||||
<p>
|
||||
<code>S9xInitSound</code> function calls this function to actually open the host sound device.
|
||||
</p>
|
||||
<h3><code>const char *S9xGetFilename (const char *extension, enum s9x_getdirtype dirtype)</code></h3>
|
||||
<p>
|
||||
When Snes9x needs to know the name of the cheat/IPS file and so on, this function is called. Check <code>extension</code> and <code>dirtype</code>, and return the appropriate filename. The current ports return the ROM file path with the given extension.
|
||||
</p>
|
||||
<h3><code>const char *S9xGetFilenameInc (const char *extension, enum s9x_getdirtype dirtype)</code></h3>
|
||||
<p>
|
||||
Almost the same as <code>S9xGetFilename</code> function, but used for saving SPC files etc. So you have to take care not to delete the previously saved file, by increasing the number of the filename; romname.000.spc, romname.001.spc, ...
|
||||
</p>
|
||||
<h3><code>const char *S9xGetDirectory (enum s9x_getdirtype dirtype)</code></h3>
|
||||
<p>
|
||||
Called when Snes9x wants to know the directory <code>dirtype</code>.
|
||||
</p>
|
||||
<h3><code>const char *S9xBasename (const char *path)</code></h3>
|
||||
<p>
|
||||
Called when Snes9x wants to know the name of the ROM image. Typically, extract the filename from <code>path</code> and return it.
|
||||
</p>
|
||||
<h3><code>void S9xAutoSaveSRAM (void)</code></h3>
|
||||
<p>
|
||||
If <code>Settings.AutoSaveDelay</code> is not zero, Snes9x calls this function when the contents of the S-RAM has been changed. Typically, call <code>Memory.SaveSRAM</code> function from this function.
|
||||
</p>
|
||||
<h3><code>void S9xToggleSoundChannel (int c)</code></h3>
|
||||
<p>
|
||||
If your port can match Snes9x's built-in <code>SoundChannelXXX</code> command (see <code>controls.cpp</code>), you may choose to use this function. Otherwise return <code>NULL</code>. Basically, turn on/off the sound channel <code>c</code> (0-7), and turn on all channels if <code>c</code> is 8.
|
||||
</p>
|
||||
<h3><code>void S9xSyncSpeed (void)</code></h3>
|
||||
<p>
|
||||
Called at the end of <code>S9xMainLoop</code> function, when emulating one frame has been done. You should adjust the frame rate in this function.
|
||||
</p>
|
||||
<h2>Global Variables</h2>
|
||||
<h3><code>uint16 *GFX.Screen</code></h3>
|
||||
<p>
|
||||
A <code>uint16</code> array pointer to (at least) 2*512*478 bytes buffer where Snes9x puts the rendered SNES screen. However, if your port will not support hires mode (<code>Settings.SupportHiRes = false</code>), then a 2*256*239 bytes buffer is allowed. You should allocate the space by yourself. As well you can change the <code>GFX.Screen</code> value after <code>S9xDeinitUpdate</code> function is called so that double-buffering will be easy.
|
||||
</p>
|
||||
<h3><code>uint32 GFX.Pitch</code></h3>
|
||||
<p>
|
||||
Bytes per line (not pixels per line) of the <code>GFX.Screen</code> buffer. Typically set it to 1024. When the SNES screen is 256 pixels width and <code>Settings.OpenGLEnable</code> is <code>false</code>, last half 512 bytes per line are unused. When <code>Settings.OpenGLEnable</code> is <code>true</code>, <code>GFX.Pitch</code> is ignored.
|
||||
</p>
|
||||
<h3>Settings structure</h3>
|
||||
<p>
|
||||
There are various switches in the <code>Settings</code> structure. See <code>snes9x.h</code> for details. At least the settings below are required for good emulation.
|
||||
</p>
|
||||
<p><code>
|
||||
memset(&Settings, 0, sizeof(Settings));<br>
|
||||
Settings.MouseMaster = true;<br>
|
||||
Settings.SuperScopeMaster = true;<br>
|
||||
Settings.JustifierMaster = true;<br>
|
||||
Settings.MultiPlayer5Master = true;<br>
|
||||
Settings.FrameTimePAL = 20000;<br>
|
||||
Settings.FrameTimeNTSC = 16667;<br>
|
||||
Settings.SoundPlaybackRate = 32040;<br>
|
||||
Settings.SoundInputRate = 31947;<br>
|
||||
Settings.SupportHiRes = true;<br>
|
||||
Settings.Transparency = true;<br>
|
||||
Settings.AutoDisplayMessages = true;<br>
|
||||
Settings.InitialInfoStringTimeout = 120;<br>
|
||||
Settings.HDMATimingHack = 100;<br>
|
||||
Settings.BlockInvalidVRAMAccessMaster = true;
|
||||
</code></p>
|
||||
<h3><code>Settings.SoundInputRate</code></h3>
|
||||
<p>
|
||||
Adjusts the sound rate through resampling. For every <code>Settings.SoundInputRate</code> samples generated by the SNES, <code>Settings.SoundPlaybackRate</code> samples will be produced.
|
||||
</p>
|
||||
<p>
|
||||
On a NTSC SNES, the video refresh rate is usually 60.09881Hz, while the audio output is 32040Hz. This means for every video frame displayed, 532.4565 sound frames are produced. A modern computer display or television will usually provide one of two video rates, 60.00Hz exactly or 59.94Hz to support broadcast television. The sound output, however, is usually fixed at exact values like 32000Hz, 44100Hz, or 48000Hz. This means that the closest video-to-sound ratio we can achieve, with 60.00Hz and 32000Hz, is 1.0/533.3333. This discrepancy means if we wait for vertical sync and update once per refresh, we will experience a sound deficit of 0.87 samples every frame, eventually causing a sound underrun and producing audio problems. <br>
|
||||
</p>
|
||||
<p>
|
||||
Settings.SoundInputRate can be set to a value such that the ratio with the video rate matches the SNES output. A 60.00Hz display, for example, should be set to 60.00 / 60.09881 * 32040, which is about 31987. The Snes9x resampler will then stretch the sound samples to fit this ratio. It may be beneficial to provide an option for users to configure <code>Settings.SoundInputRate</code> to suit their own systems. Setting <code>Settings.SoundInputRate</code> to a value that matches the actual output rate (i.e. 31915hz for 59.94Hz) or lower will allow the users to eliminate crackling. A range of 31000hz to 33000hz should be inclusive enough for all displays. Use of this setting paired with the <code>S9xSyncSound</code> function can eliminate sound discontinuity. However, this concept is difficult for most users to understand. If possible, read the display's refresh rate and automatically calculate the appropriate input rate by default. In practice, few displays exceed a target of 60.00Hz, so a good default would be no greater than 31950Hz, but probably lower.
|
||||
</p>
|
||||
<h3><code>Settings.DynamicRateControl</code> and <code>S9xUpdateDynamicRate(int numerator, int denominator)</code></h3>
|
||||
<p>
|
||||
To eliminate buffer overflows and underflows, dynamic rate control can be implemented and used. While this can accommodate for Settings.SoundInputRate not being set correctly, it works better the closer that value is to ideal.
|
||||
</p>
|
||||
<p>
|
||||
To implement, set <code>Settings.DynamicRateControl</code> to <code>true</code>. At the beginning of your <code>samples_available</code> callback, check the hardware output buffer's fill level. Report the amount of free space in the buffer as a fraction of total buffer size to <code>S9xUpdateDynamicRate</code>, and Snes9x will try and keep the buffer close to 50% full. To tune this, <code>Settings.DynamicRateLimit</code> can be changed. A larger value will increase the range of frequencies it can use, but will also cause more noticeable pitch changes.

***** Important notice ********************************************************
|
||||
This document describes the snapshot file format for Snes9x 1.52 and later,
|
||||
not compatible with 1.51.
|
||||
*******************************************************************************
|
||||
|
||||
Snes9x snapshot file format: (may be gzip-compressed)
|
||||
|
||||
Begins with fixed length signature, consisting of a string, ':', a 4-digit
|
||||
decimal version, and a '\n'.
|
||||
|
||||
#!s9xsnp:0006 <-- '\n' after the 6
|
||||
|
||||
Then we have various blocks. The block format is: 3-character block name,
|
||||
':', 6-digit length, ':', then the data. Blocks are written in a defined
|
||||
order. Structs are written packed with their members in a defined order, in
|
||||
big-endian order where applicable.
|
||||
|
||||
NAM:000019:Chrono Trigger.zip
|
||||
|
||||
Currently defined blocks (in order) are:
|
||||
|
||||
Essential parts:
|
||||
NAM - ROM filename, from Memory.ROMFilename. 0-terminated string.
|
||||
CPU - struct SCPUState, CPU internal state variables.
|
||||
REG - struct SRegisters, emulated CPU registers.
|
||||
PPU - struct SPPU, PPU internal variables. Note that IPPU is never saved.
|
||||
DMA - struct SDMA, DMA/HDMA state variables.
|
||||

|
||||
CTL - struct SControlSnapshot, controller emulation.
|
||||

|
||||
|
||||
Optional parts:
|
||||

|
||||
|
||||
==================
|
||||
|
||||
Without changing the snapshot version number:
|
||||
---------------------------------------------
|
||||
|
||||
Blocks may be safely added at the END of the file, as anything after the last
|
||||
block is ignored. Blocks may not be moved or removed.
|
||||
|
||||
Blocks may not decrease in size. Say you decrease from 10 bytes to 5. Then
|
||||
later you increase back to 8. The only way you could safely do this is if
|
||||
bytes 5-7 still mean the same thing they meant when the block was 10 bytes
|
||||
long.
|
||||
|
||||
Blocks may increase in size as you wish, as long as you can handle old
|
||||
savestates with the old shorter size.
|
||||
|
||||
Struct members may not change in interpretation. New struct members may be
|
||||
added (at the END!) only if you can cope with them being binary-0 in older
|
||||
savestates. Struct members may not be removed or changed in size/type.
|
||||
|
||||
With changing the snapshot version number:
|
||||
------------------------------------------
|
||||
|
||||
Blocks may be added, moved, or removed at will.
|
||||
|
||||
Blocks may decrease in size.
|
||||
|
||||
Struct members may be added, moved, or deleted, and their
|
||||
interpretations/types may be changed. Use the 'debuted_in' and 'deleted_in'
|
||||
fields to indicate when the new member debuted or the old member went away.

GNU GENERAL PUBLIC LICENSE
|
||||
Version 3, 29 June 2007
|
||||
|
||||
Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
Preamble
|
||||
|
||||
The GNU General Public License is a free, copyleft license for
|
||||
software and other kinds of works.
|
||||
|
||||
The licenses for most software and other practical works are designed
|
||||
to take away your freedom to share and change the works. By contrast,
|
||||
the GNU General Public License is intended to guarantee your freedom to
|
||||
share and change all versions of a program--to make sure it remains free
|
||||
software for all its users. We, the Free Software Foundation, use the
|
||||
GNU General Public License for most of our software; it applies also to
|
||||
any other work released this way by its authors. You can apply it to
|
||||
your programs, too.
|
||||
|
||||
When we speak of free software, we are referring to freedom, not
|
||||
price. Our General Public Licenses are designed to make sure that you
|
||||
have the freedom to distribute copies of free software (and charge for
|
||||
them if you wish), that you receive source code or can get it if you
|
||||
want it, that you can change the software or use pieces of it in new
|
||||
free programs, and that you know you can do these things.
|
||||
|
||||
To protect your rights, we need to prevent others from denying you
|
||||
these rights or asking you to surrender the rights. Therefore, you have
|
||||
certain responsibilities if you distribute copies of the software, or if
|
||||
you modify it: responsibilities to respect the freedom of others.
|
||||
|
||||
For example, if you distribute copies of such a program, whether
|
||||
gratis or for a fee, you must pass on to the recipients the same
|
||||
freedoms that you received. You must make sure that they, too, receive
|
||||
or can get the source code. And you must show them these terms so they
|
||||
know their rights.
|
||||
|
||||
Developers that use the GNU GPL protect your rights with two steps:
|
||||
(1) assert copyright on the software, and (2) offer you this License
|
||||
giving you legal permission to copy, distribute and/or modify it.
|
||||
|
||||
For the developers' and authors' protection, the GPL clearly explains
|
||||
that there is no warranty for this free software. For both users' and
|
||||
authors' sake, the GPL requires that modified versions be marked as
|
||||
changed, so that their problems will not be attributed erroneously to
|
||||
authors of previous versions.
|
||||
|
||||
Some devices are designed to deny users access to install or run
|
||||
modified versions of the software inside them, although the manufacturer
|
||||
can do so. This is fundamentally incompatible with the aim of
|
||||
protecting users' freedom to change the software. The systematic
|
||||
pattern of such abuse occurs in the area of products for individuals to
|
||||
use, which is precisely where it is most unacceptable. Therefore, we
|
||||
have designed this version of the GPL to prohibit the practice for those
|
||||
products. If such problems arise substantially in other domains, we
|
||||
stand ready to extend this provision to those domains in future versions
|
||||
of the GPL, as needed to protect the freedom of users.
|
||||
|
||||
Finally, every program is threatened constantly by software patents.
|
||||
States should not allow patents to restrict development and use of
|
||||
software on general-purpose computers, but in those that do, we wish to
|
||||
avoid the special danger that patents applied to a free program could
|
||||
make it effectively proprietary. To prevent this, the GPL assures that
|
||||
patents cannot be used to render the program non-free.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow.
|
||||
|
||||
TERMS AND CONDITIONS
|
||||
|
||||
0. Definitions.
|
||||
|
||||
"This License" refers to version 3 of the GNU General Public License.
|
||||
|
||||
"Copyright" also means copyright-like laws that apply to other kinds of
|
||||
works, such as semiconductor masks.
|
||||
|
||||
"The Program" refers to any copyrightable work licensed under this
|
||||
License. Each licensee is addressed as "you". "Licensees" and
|
||||
"recipients" may be individuals or organizations.
|
||||
|
||||
To "modify" a work means to copy from or adapt all or part of the work
|
||||
in a fashion requiring copyright permission, other than the making of an
|
||||
exact copy. The resulting work is called a "modified version" of the
|
||||
earlier work or a work "based on" the earlier work.
|
||||
|
||||
A "covered work" means either the unmodified Program or a work based
|
||||
on the Program.
|
||||
|
||||
To "propagate" a work means to do anything with it that, without
|
||||
permission, would make you directly or secondarily liable for
|
||||
infringement under applicable copyright law, except executing it on a
|
||||
computer or modifying a private copy. Propagation includes copying,
|
||||
distribution (with or without modification), making available to the
|
||||
public, and in some countries other activities as well.
|
||||
|
||||
To "convey" a work means any kind of propagation that enables other
|
||||
parties to make or receive copies. Mere interaction with a user through
|
||||
a computer network, with no transfer of a copy, is not conveying.
|
||||
|
||||
An interactive user interface displays "Appropriate Legal Notices"
|
||||
to the extent that it includes a convenient and prominently visible
|
||||
feature that (1) displays an appropriate copyright notice, and (2)
|
||||
tells the user that there is no warranty for the work (except to the
|
||||
extent that warranties are provided), that licensees may convey the
|
||||
work under this License, and how to view a copy of this License. If
|
||||
the interface presents a list of user commands or options, such as a
|
||||
menu, a prominent item in the list meets this criterion.
|
||||
|
||||
1. Source Code.
|
||||
|
||||
The "source code" for a work means the preferred form of the work
|
||||
for making modifications to it. "Object code" means any non-source
|
||||
form of a work.
|
||||
|
||||
A "Standard Interface" means an interface that either is an official
|
||||
standard defined by a recognized standards body, or, in the case of
|
||||
interfaces specified for a particular programming language, one that
|
||||
is widely used among developers working in that language.
|
||||
|
||||
The "System Libraries" of an executable work include anything, other
|
||||
than the work as a whole, that (a) is included in the normal form of
|
||||
packaging a Major Component, but which is not part of that Major
|
||||
Component, and (b) serves only to enable use of the work with that
|
||||
Major Component, or to implement a Standard Interface for which an
|
||||
implementation is available to the public in source code form. A
|
||||
"Major Component", in this context, means a major essential component
|
||||
(kernel, window system, and so on) of the specific operating system
|
||||
(if any) on which the executable work runs, or a compiler used to
|
||||
produce the work, or an object code interpreter used to run it.
|
||||
|
||||
The "Corresponding Source" for a work in object code form means all
|
||||
the source code needed to generate, install, and (for an executable
|
||||
work) run the object code and to modify the work, including scripts to
|
||||
control those activities. However, it does not include the work's
|
||||
System Libraries, or general-purpose tools or generally available free
|
||||
programs which are used unmodified in performing those activities but
|
||||
which are not part of the work. For example, Corresponding Source
|
||||
includes interface definition files associated with source files for
|
||||
the work, and the source code for shared libraries and dynamically
|
||||
linked subprograms that the work is specifically designed to require,
|
||||
such as by intimate data communication or control flow between those
|
||||
subprograms and other parts of the work.
|
||||
|
||||
The Corresponding Source need not include anything that users
|
||||
can regenerate automatically from other parts of the Corresponding
|
||||
Source.
|
||||
|
||||
The Corresponding Source for a work in source code form is that
|
||||
same work.
|
||||
|
||||
2. Basic Permissions.
|
||||
|
||||
All rights granted under this License are granted for the term of
|
||||
copyright on the Program, and are irrevocable provided the stated
|
||||
conditions are met. This License explicitly affirms your unlimited
|
||||
permission to run the unmodified Program. The output from running a
|
||||
covered work is covered by this License only if the output, given its
|
||||
content, constitutes a covered work. This License acknowledges your
|
||||
rights of fair use or other equivalent, as provided by copyright law.
|
||||
|
||||
You may make, run and propagate covered works that you do not
|
||||
convey, without conditions so long as your license otherwise remains
|
||||
in force. You may convey covered works to others for the sole purpose
|
||||
of having them make modifications exclusively for you, or provide you
|
||||
with facilities for running those works, provided that you comply with
|
||||
the terms of this License in conveying all material for which you do
|
||||
not control copyright. Those thus making or running the covered works
|
||||
for you must do so exclusively on your behalf, under your direction
|
||||
and control, on terms that prohibit them from making any copies of
|
||||
your copyrighted material outside their relationship with you.
|
||||
|
||||
Conveying under any other circumstances is permitted solely under
|
||||
the conditions stated below. Sublicensing is not allowed; section 10
|
||||
makes it unnecessary.
|
||||
|
||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||
|
||||
No covered work shall be deemed part of an effective technological
|
||||
measure under any applicable law fulfilling obligations under article
|
||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or
|
||||
similar laws prohibiting or restricting circumvention of such
|
||||
measures.
|
||||
|
||||
When you convey a covered work, you waive any legal power to forbid
|
||||
circumvention of technological measures to the extent such circumvention
|
||||
is effected by exercising rights under this License with respect to
|
||||
the covered work, and you disclaim any intention to limit operation or
|
||||
modification of the work as a means of enforcing, against the work's
|
||||
users, your or third parties' legal rights to forbid circumvention of
|
||||
technological measures.
|
||||
|
||||
4. Conveying Verbatim Copies.
|
||||
|
||||
You may convey verbatim copies of the Program's source code as you
|
||||
receive it, in any medium, provided that you conspicuously and
|
||||
appropriately publish on each copy an appropriate copyright notice;
|
||||
keep intact all notices stating that this License and any
|
||||
non-permissive terms added in accord with section 7 apply to the code;
|
||||
keep intact all notices of the absence of any warranty; and give all
|
||||
recipients a copy of this License along with the Program.
|
||||
|
||||
You may charge any price or no price for each copy that you convey,
|
||||
and you may offer support or warranty protection for a fee.
|
||||
|
||||
5. Conveying Modified Source Versions.
|
||||
|
||||
You may convey a work based on the Program, or the modifications to
|
||||
produce it from the Program, in the form of source code under the
|
||||
terms of section 4, provided that you also meet all of these conditions:
|
||||
|
||||
a) The work must carry prominent notices stating that you modified
|
||||
it, and giving a relevant date.
|
||||
|
||||
b) The work must carry prominent notices stating that it is
|
||||
released under this License and any conditions added under section
|
||||
7. This requirement modifies the requirement in section 4 to
|
||||
"keep intact all notices".
|
||||
|
||||
c) You must license the entire work, as a whole, under this
|
||||
License to anyone who comes into possession of a copy. This
|
||||
License will therefore apply, along with any applicable section 7
|
||||
additional terms, to the whole of the work, and all its parts,
|
||||
regardless of how they are packaged. This License gives no
|
||||
permission to license the work in any other way, but it does not
|
||||
invalidate such permission if you have separately received it.
|
||||
|
||||
d) If the work has interactive user interfaces, each must display
|
||||
Appropriate Legal Notices; however, if the Program has interactive
|
||||
interfaces that do not display Appropriate Legal Notices, your
|
||||
work need not make them do so.
|
||||
|
||||
A compilation of a covered work with other separate and independent
|
||||
works, which are not by their nature extensions of the covered work,
|
||||
and which are not combined with it such as to form a larger program,
|
||||
in or on a volume of a storage or distribution medium, is called an
|
||||
"aggregate" if the compilation and its resulting copyright are not
|
||||
used to limit the access or legal rights of the compilation's users
|
||||
beyond what the individual works permit. Inclusion of a covered work
|
||||
in an aggregate does not cause this License to apply to the other
|
||||
parts of the aggregate.
|
||||
|
||||
6. Conveying Non-Source Forms.
|
||||
|
||||
You may convey a covered work in object code form under the terms
|
||||
of sections 4 and 5, provided that you also convey the
|
||||
machine-readable Corresponding Source under the terms of this License,
|
||||
in one of these ways:
|
||||
|
||||
a) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by the
|
||||
Corresponding Source fixed on a durable physical medium
|
||||
customarily used for software interchange.
|
||||
|
||||
b) Convey the object code in, or embodied in, a physical product
|
||||
(including a physical distribution medium), accompanied by a
|
||||
written offer, valid for at least three years and valid for as
|
||||
long as you offer spare parts or customer support for that product
|
||||
model, to give anyone who possesses the object code either (1) a
|
||||
copy of the Corresponding Source for all the software in the
|
||||
product that is covered by this License, on a durable physical
|
||||
medium customarily used for software interchange, for a price no
|
||||
more than your reasonable cost of physically performing this
|
||||
conveying of source, or (2) access to copy the
|
||||
Corresponding Source from a network server at no charge.
|
||||
|
||||
c) Convey individual copies of the object code with a copy of the
|
||||
written offer to provide the Corresponding Source. This
|
||||
alternative is allowed only occasionally and noncommercially, and
|
||||
only if you received the object code with such an offer, in accord
|
||||
with subsection 6b.
|
||||
|
||||
d) Convey the object code by offering access from a designated
|
||||
place (gratis or for a charge), and offer equivalent access to the
|
||||
Corresponding Source in the same way through the same place at no
|
||||
further charge. You need not require recipients to copy the
|
||||
Corresponding Source along with the object code. If the place to
|
||||
copy the object code is a network server, the Corresponding Source
|
||||
may be on a different server (operated by you or a third party)
|
||||
that supports equivalent copying facilities, provided you maintain
|
||||
clear directions next to the object code saying where to find the
|
||||
Corresponding Source. Regardless of what server hosts the
|
||||
Corresponding Source, you remain obligated to ensure that it is
|
||||
available for as long as needed to satisfy these requirements.
|
||||
|
||||
e) Convey the object code using peer-to-peer transmission, provided
|
||||
you inform other peers where the object code and Corresponding
|
||||
Source of the work are being offered to the general public at no
|
||||
charge under subsection 6d.
|
||||
|
||||
A separable portion of the object code, whose source code is excluded
|
||||
from the Corresponding Source as a System Library, need not be
|
||||
included in conveying the object code work.
|
||||
|
||||
A "User Product" is either (1) a "consumer product", which means any
|
||||
tangible personal property which is normally used for personal, family,
|
||||
or household purposes, or (2) anything designed or sold for incorporation
|
||||
into a dwelling. In determining whether a product is a consumer product,
|
||||
doubtful cases shall be resolved in favor of coverage. For a particular
|
||||
product received by a particular user, "normally used" refers to a
|
||||
typical or common use of that class of product, regardless of the status
|
||||
of the particular user or of the way in which the particular user
|
||||
actually uses, or expects or is expected to use, the product. A product
|
||||
is a consumer product regardless of whether the product has substantial
|
||||
commercial, industrial or non-consumer uses, unless such uses represent
|
||||
the only significant mode of use of the product.
|
||||
|
||||
"Installation Information" for a User Product means any methods,
|
||||
procedures, authorization keys, or other information required to install
|
||||
and execute modified versions of a covered work in that User Product from
|
||||
a modified version of its Corresponding Source. The information must
|
||||
suffice to ensure that the continued functioning of the modified object
|
||||
code is in no case prevented or interfered with solely because
|
||||
modification has been made.
|
||||
|
||||
If you convey an object code work under this section in, or with, or
|
||||
specifically for use in, a User Product, and the conveying occurs as
|
||||
part of a transaction in which the right of possession and use of the
|
||||
User Product is transferred to the recipient in perpetuity or for a
|
||||
fixed term (regardless of how the transaction is characterized), the
|
||||
Corresponding Source conveyed under this section must be accompanied
|
||||
by the Installation Information. But this requirement does not apply
|
||||
if neither you nor any third party retains the ability to install
|
||||
modified object code on the User Product (for example, the work has
|
||||
been installed in ROM).
|
||||
|
||||
The requirement to provide Installation Information does not include a
|
||||
requirement to continue to provide support service, warranty, or updates
|
||||
for a work that has been modified or installed by the recipient, or for
|
||||
the User Product in which it has been modified or installed. Access to a
|
||||
network may be denied when the modification itself materially and
|
||||
adversely affects the operation of the network or violates the rules and
|
||||
protocols for communication across the network.
|
||||
|
||||
Corresponding Source conveyed, and Installation Information provided,
|
||||
in accord with this section must be in a format that is publicly
|
||||
documented (and with an implementation available to the public in
|
||||
source code form), and must require no special password or key for
|
||||
unpacking, reading or copying.
|
||||
|
||||
7. Additional Terms.
|
||||
|
||||
"Additional permissions" are terms that supplement the terms of this
|
||||
License by making exceptions from one or more of its conditions.
|
||||
Additional permissions that are applicable to the entire Program shall
|
||||
be treated as though they were included in this License, to the extent
|
||||
that they are valid under applicable law. If additional permissions
|
||||
apply only to part of the Program, that part may be used separately
|
||||
under those permissions, but the entire Program remains governed by
|
||||
this License without regard to the additional permissions.
|
||||
|
||||
When you convey a copy of a covered work, you may at your option
|
||||
remove any additional permissions from that copy, or from any part of
|
||||
it. (Additional permissions may be written to require their own
|
||||
removal in certain cases when you modify the work.) You may place
|
||||
additional permissions on material, added by you to a covered work,
|
||||
for which you have or can give appropriate copyright permission.
|
||||
|
||||
Notwithstanding any other provision of this License, for material you
|
||||
add to a covered work, you may (if authorized by the copyright holders of
|
||||
that material) supplement the terms of this License with terms:
|
||||
|
||||
a) Disclaiming warranty or limiting liability differently from the
|
||||
terms of sections 15 and 16 of this License; or
|
||||
|
||||
b) Requiring preservation of specified reasonable legal notices or
|
||||
author attributions in that material or in the Appropriate Legal
|
||||
Notices displayed by works containing it; or
|
||||
|
||||
c) Prohibiting misrepresentation of the origin of that material, or
|
||||
requiring that modified versions of such material be marked in
|
||||
reasonable ways as different from the original version; or
|
||||
|
||||
d) Limiting the use for publicity purposes of names of licensors or
|
||||
authors of the material; or
|
||||
|
||||
e) Declining to grant rights under trademark law for use of some
|
||||
trade names, trademarks, or service marks; or
|
||||
|
||||
f) Requiring indemnification of licensors and authors of that
|
||||
material by anyone who conveys the material (or modified versions of
|
||||
it) with contractual assumptions of liability to the recipient, for
|
||||
any liability that these contractual assumptions directly impose on
|
||||
those licensors and authors.
|
||||
|
||||
All other non-permissive additional terms are considered "further
|
||||
restrictions" within the meaning of section 10. If the Program as you
|
||||
received it, or any part of it, contains a notice stating that it is
|
||||
governed by this License along with a term that is a further
|
||||
restriction, you may remove that term. If a license document contains
|
||||
a further restriction but permits relicensing or conveying under this
|
||||
License, you may add to a covered work material governed by the terms
|
||||
of that license document, provided that the further restriction does
|
||||
not survive such relicensing or conveying.
|
||||
|
||||
If you add terms to a covered work in accord with this section, you
|
||||
must place, in the relevant source files, a statement of the
|
||||
additional terms that apply to those files, or a notice indicating
|
||||
where to find the applicable terms.
|
||||
|
||||
Additional terms, permissive or non-permissive, may be stated in the
|
||||
form of a separately written license, or stated as exceptions;
|
||||
the above requirements apply either way.
|
||||
|
||||
8. Termination.
|
||||
|
||||
You may not propagate or modify a covered work except as expressly
|
||||
provided under this License. Any attempt otherwise to propagate or
|
||||
modify it is void, and will automatically terminate your rights under
|
||||
this License (including any patent licenses granted under the third
|
||||
paragraph of section 11).
|
||||
|
||||
However, if you cease all violation of this License, then your
|
||||
license from a particular copyright holder is reinstated (a)
|
||||
provisionally, unless and until the copyright holder explicitly and
|
||||
finally terminates your license, and (b) permanently, if the copyright
|
||||
holder fails to notify you of the violation by some reasonable means
|
||||
prior to 60 days after the cessation.
|
||||
|
||||
Moreover, your license from a particular copyright holder is
|
||||
reinstated permanently if the copyright holder notifies you of the
|
||||
violation by some reasonable means, this is the first time you have
|
||||
received notice of violation of this License (for any work) from that
|
||||
copyright holder, and you cure the violation prior to 30 days after
|
||||
your receipt of the notice.
|
||||
|
||||
Termination of your rights under this section does not terminate the
|
||||
licenses of parties who have received copies or rights from you under
|
||||
this License. If your rights have been terminated and not permanently
|
||||
reinstated, you do not qualify to receive new licenses for the same
|
||||
material under section 10.
|
||||
|
||||
9. Acceptance Not Required for Having Copies.
|
||||
|
||||
You are not required to accept this License in order to receive or
|
||||
run a copy of the Program. Ancillary propagation of a covered work
|
||||
occurring solely as a consequence of using peer-to-peer transmission
|
||||
to receive a copy likewise does not require acceptance. However,
|
||||
nothing other than this License grants you permission to propagate or
|
||||
modify any covered work. These actions infringe copyright if you do
|
||||
not accept this License. Therefore, by modifying or propagating a
|
||||
covered work, you indicate your acceptance of this License to do so.
|
||||
|
||||
10. Automatic Licensing of Downstream Recipients.
|
||||
|
||||
Each time you convey a covered work, the recipient automatically
|
||||
receives a license from the original licensors, to run, modify and
|
||||
propagate that work, subject to this License. You are not responsible
|
||||
for enforcing compliance by third parties with this License.
|
||||
|
||||
An "entity transaction" is a transaction transferring control of an
|
||||
organization, or substantially all assets of one, or subdividing an
|
||||
organization, or merging organizations. If propagation of a covered
|
||||
work results from an entity transaction, each party to that
|
||||
transaction who receives a copy of the work also receives whatever
|
||||
licenses to the work the party's predecessor in interest had or could
|
||||
give under the previous paragraph, plus a right to possession of the
|
||||
Corresponding Source of the work from the predecessor in interest, if
|
||||
the predecessor has it or can get it with reasonable efforts.
|
||||
|
||||
You may not impose any further restrictions on the exercise of the
|
||||
rights granted or affirmed under this License. For example, you may
|
||||
not impose a license fee, royalty, or other charge for exercise of
|
||||
rights granted under this License, and you may not initiate litigation
|
||||
(including a cross-claim or counterclaim in a lawsuit) alleging that
|
||||
any patent claim is infringed by making, using, selling, offering for
|
||||
sale, or importing the Program or any portion of it.
|
||||
|
||||
11. Patents.
|
||||
|
||||
A "contributor" is a copyright holder who authorizes use under this
|
||||
License of the Program or a work on which the Program is based. The
|
||||
work thus licensed is called the contributor's "contributor version".
|
||||
|
||||
A contributor's "essential patent claims" are all patent claims
|
||||
owned or controlled by the contributor, whether already acquired or
|
||||
hereafter acquired, that would be infringed by some manner, permitted
|
||||
by this License, of making, using, or selling its contributor version,
|
||||
but do not include claims that would be infringed only as a
|
||||
consequence of further modification of the contributor version. For
|
||||
purposes of this definition, "control" includes the right to grant
|
||||
patent sublicenses in a manner consistent with the requirements of
|
||||
this License.
|
||||
|
||||
Each contributor grants you a non-exclusive, worldwide, royalty-free
|
||||
patent license under the contributor's essential patent claims, to
|
||||
make, use, sell, offer for sale, import and otherwise run, modify and
|
||||
propagate the contents of its contributor version.
|
||||
|
||||
In the following three paragraphs, a "patent license" is any express
|
||||
agreement or commitment, however denominated, not to enforce a patent
|
||||
(such as an express permission to practice a patent or covenant not to
|
||||
sue for patent infringement). To "grant" such a patent license to a
|
||||
party means to make such an agreement or commitment not to enforce a
|
||||
patent against the party.
|
||||
|
||||
If you convey a covered work, knowingly relying on a patent license,
|
||||
and the Corresponding Source of the work is not available for anyone
|
||||
to copy, free of charge and under the terms of this License, through a
|
||||
publicly available network server or other readily accessible means,
|
||||
then you must either (1) cause the Corresponding Source to be so
|
||||
available, or (2) arrange to deprive yourself of the benefit of the
|
||||
patent license for this particular work, or (3) arrange, in a manner
|
||||
consistent with the requirements of this License, to extend the patent
|
||||
license to downstream recipients. "Knowingly relying" means you have
|
||||
actual knowledge that, but for the patent license, your conveying the
|
||||
covered work in a country, or your recipient's use of the covered work
|
||||
in a country, would infringe one or more identifiable patents in that
|
||||
country that you have reason to believe are valid.
|
||||
|
||||
If, pursuant to or in connection with a single transaction or
|
||||
arrangement, you convey, or propagate by procuring conveyance of, a
|
||||
covered work, and grant a patent license to some of the parties
|
||||
receiving the covered work authorizing them to use, propagate, modify
|
||||
or convey a specific copy of the covered work, then the patent license
|
||||
you grant is automatically extended to all recipients of the covered
|
||||
work and works based on it.
|
||||
|
||||
A patent license is "discriminatory" if it does not include within
|
||||
the scope of its coverage, prohibits the exercise of, or is
|
||||
conditioned on the non-exercise of one or more of the rights that are
|
||||
specifically granted under this License. You may not convey a covered
|
||||
work if you are a party to an arrangement with a third party that is
|
||||
in the business of distributing software, under which you make payment
|
||||
to the third party based on the extent of your activity of conveying
|
||||
the work, and under which the third party grants, to any of the
|
||||
parties who would receive the covered work from you, a discriminatory
|
||||
patent license (a) in connection with copies of the covered work
|
||||
conveyed by you (or copies made from those copies), or (b) primarily
|
||||
for and in connection with specific products or compilations that
|
||||
contain the covered work, unless you entered into that arrangement,
|
||||
or that patent license was granted, prior to 28 March 2007.
|
||||
|
||||
Nothing in this License shall be construed as excluding or limiting
|
||||
any implied license or other defenses to infringement that may
|
||||
otherwise be available to you under applicable patent law.
|
||||
|
||||
12. No Surrender of Others' Freedom.
|
||||
|
||||
If conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot convey a
|
||||
covered work so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you may
|
||||
not convey it at all. For example, if you agree to terms that obligate you
|
||||
to collect a royalty for further conveying from those to whom you convey
|
||||
the Program, the only way you could satisfy both those terms and this
|
||||
License would be to refrain entirely from conveying the Program.
|
||||
|
||||
13. Use with the GNU Affero General Public License.
|
||||
|
||||
Notwithstanding any other provision of this License, you have
|
||||
permission to link or combine any covered work with a work licensed
|
||||
under version 3 of the GNU Affero General Public License into a single
|
||||
combined work, and to convey the resulting work. The terms of this
|
||||
License will continue to apply to the part which is the covered work,
|
||||
but the special requirements of the GNU Affero General Public License,
|
||||
section 13, concerning interaction through a network will apply to the
|
||||
combination as such.
|
||||
|
||||
14. Revised Versions of this License.
|
||||
|
||||
The Free Software Foundation may publish revised and/or new versions of
|
||||
the GNU General Public License from time to time. Such new versions will
|
||||
be similar in spirit to the present version, but may differ in detail to
|
||||
address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the
|
||||
Program specifies that a certain numbered version of the GNU General
|
||||
Public License "or any later version" applies to it, you have the
|
||||
option of following the terms and conditions either of that numbered
|
||||
version or of any later version published by the Free Software
|
||||
Foundation. If the Program does not specify a version number of the
|
||||
GNU General Public License, you may choose any version ever published
|
||||
by the Free Software Foundation.
|
||||
|
||||
If the Program specifies that a proxy can decide which future
|
||||
versions of the GNU General Public License can be used, that proxy's
|
||||
public statement of acceptance of a version permanently authorizes you
|
||||
to choose that version for the Program.
|
||||
|
||||
Later license versions may give you additional or different
|
||||
permissions. However, no additional obligations are imposed on any
|
||||
author or copyright holder as a result of your choosing to follow a
|
||||
later version.
|
||||
|
||||
15. Disclaimer of Warranty.
|
||||
|
||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
|
||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
|
||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
|
||||
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
|
||||
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
|
||||
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
|
||||
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. Limitation of Liability.
|
||||
|
||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
|
||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
|
||||
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
|
||||
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
|
||||
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
|
||||
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
|
||||
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
|
||||
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
|
||||
SUCH DAMAGES.
|
||||
|
||||
17. Interpretation of Sections 15 and 16.
|
||||
|
||||
If the disclaimer of warranty and limitation of liability provided
|
||||
above cannot be given local legal effect according to their terms,
|
||||
reviewing courts shall apply local law that most closely approximates
|
||||
an absolute waiver of all civil liability in connection with the
|
||||
Program, unless a warranty or assumption of liability accompanies a
|
||||
copy of the Program in return for a fee.

THREAD-SAFETY: - parts of the same image may be scaled by multiple threads as long as the [yFirst, yLast) ranges do not overlap!
