DOES THE MUSIC SOUND CRAPPY IN YOUR OLD 80'S / 90'S PC GAMES?
FatBoy was created specifically to make MIDI sound better. Hopefully, a lotbetter. Any games which utilize MIDI-based soundtracks will sound dramatically different with FatBoy.
I would not be surprised if several of the general midi instruments available in this one sound suspiciously familiar, but still there may be some gems of interest.
