It has a great interface, and even supports RAR-compressed music files. WinAMP plugin that features the Neon core, which doesn't sound bad at all. This utility converts the Genecyst GYM music file to a standard MIDI to be played in any midi program. This is a very useful utility if you want to create Genesis music MIDIs, but want to have something to work with, rather than start from scratch.

This is one of the first ever GYM players. The sound is average since it lacks PCM support. Has support for skinning. For those who like multi sound format players, give this player a go. It allows WinAMP to play Genesis GYM and Callus CYM music files.
