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)
* 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.

Changes:

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
