XPMCK is a music (expressed in MML) compiler kit targeted towards various video game systems. It currently supports the following systems:

• Capcom Play System (VGM output)
• ColecoVision
• Commodore 64
• Nintendo Gameboy / Gameboy Color
• SEGA Master System
• SEGA Game Gear
• SEGA Genesis

Besides the compiler and its source code, the kit includes playback libraries for all supported systems, as well as examples and brief documentation.

2009-05-26:

• Implemented a more efficient way of storing note lengths. Compiled music data is now a lot smaller (typically 10-50% smaller, depending on the music structure and what other commands are used).
• Modified the frequency data used for the YM2612.
• Code for handling unused effects is now excluded on a per-channel basis when compiling the playback libraries, which cuts down the code size a bit in some cases.
• Updated the GUI to include ColecoVision as a target.

2009-04-17:

• Added the ColecoVision as a supported target (I get really strange sound output from ColEm. But it works in blueMSX).

2009-03-02:

• Added support for periodic noise on the GBC (noise counter width change).
• Extended the octave range of the GBC noise channel (can now go from octave 1 to octave 9).
• Fixed a bug in the Genesis (Z80) playback library where volume macros wouldn't be turned off properly.
• Fixed a bug in the pattern handling in the GBC playback library

2008-12-27:

• Added support for default parameters for macros.
• Added support for patterns.
• Added support for detuning to the C64 playback library.
• Added support for EP and MP to the C64 playback library.
• Updated the GUI.

2008-11-18:

• Tempo settings up to 300 BPM are now supported.
• Fixed some bugs in the handling of duty cycle macros in the GBC player.
• Channel 3 on the GBC is now allowed to go down to C in octave 1.

2008-08-25:

• Added playback code for the Commodore 64.
• Added CPS-1 as a supported target (YM2151. VGM output only).
• The compiler now outputs header information to be used when creating .gbs/.sid files (C64, GBC).
• Volume is now applied individually per operator (Genesis).
• Added support for SSG envelope generation (Genesis).

2008-08-05:

• Added support for PCM playback on SEGA Genesis channel J (only when outputting to VGM).
• Added support for non-standard note lengths (3, 6, 12 and 24).
• A .vgm file is now created for each song in a multisong MML when outputting to VGM.
• Fixed a bug that sometimes could occur when using &.

2008-08-03:

• Added support for amplitude modulation (using the MOD and AM commands) to the SEGA Genesis playback library.
• Added support for panning to the Gameboy playback library.
• Added a command, k, for specifying the length of notes in number of 32nd notes.
• Fixed a bug in the way the SEGA Genesis playback library handled ADSR commands.
• Fixed the handling of CSOF in the Gamegear playback library.

2008-07-20:

• Added support for the @te and @ve command to the Gameboy playback library.
• Fixed some bugs in the Gameboy playback library.
• Fixed a bug in the Genesis playback library.
• Fixed the include path handling so that it is relative to the path of the includer (unless an absolute path is specified).
• Unused effects are now automatically removed by the compiler.
• Updated the manual.

2008-07-13:

• Added support for the FM-portion of @MOD to the SEGA Genesis playback library.
• Updated the GUI.
• Updated the manual.
• The compiler is now a Win32 console application instead of a DOS application; no more 8.3 filenames.

2008-07-08:

• Added playback code for the Gameboy / Gameboy Color.
• Added an @FBM command (macro version of FB).
• Algorithm macros (@@) can now be used on the SEGA Genesis FM channels.

2008-07-04:

• Added playback code for the SEGA Genesis.

2008-06-28:

• Added an RS command for FM channels (rate scaling).
• Added a simple GUI (mcgui.exe).
• Fixed some bugs in @ADSR. Sustain was inverted compared to how it was described in the manual, and sustain and release also weren't shifted correctly.
• Fixed the implementation of D (detune) for the SEGA Genesis FM channels.

2008-06-26:

• Added the possibility for simple logic in #IFDEF/#IFNDEF/#ELSIFDEF expressions (e.g #IFDEF SMS|SGG).
• Added #ERROR and #WARNING.
• Added several commands related to FM chips (YM2413, YM2612).
• Added SEGA Genesis as a supported target (only VGM output, no sound driver has been written yet).
• Fixed some bugs in the way #ELSE and #ELSIFDEF were handled.
• Fixed a bug in [] when multiple channels were active.
• You now get a warning from the compiler if you try to specify the length of a note inside of a tuple.
• Cleaned up the code a bit in the SMS and GG test programs.
