I've been playing around with DOSBox GUS support, and I was wondering if anyone had a list of games where GUS output is clearly better than MIDI (via fluidsynth/soundfonts) or MT32. I've found a few lists of games with native GUS support, but so far the GUS music has not been better than MIDI with a good soundfont. I suppose the GUS should theoretically do better than soundblaster with MOD music, so I would guess that games with MOD music would sound better on GUS if it was fully supported.
EDIT:
Here's the list so far of games that IMO sound better on GUS:
Pinball Dreams, Pinball Fantasies, Epic Pinball, Silverball, Jazz Jackrabbit, and Raptor.
I've still got a few more games to try, but it mainly appears that games with tracker music sound better on GUS.
