2009-08-10:

2009-07-06:

Added KSS as a supported target (only the SN76489 can be used at the moment).

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:

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.
