I had a good hacking opportunity on this game as well - a chap named Ravi Iyengar made a General MIDI sound driver you could drop into these SCI0 games (apparently they all did MT-32, but none did General Midi, and the driver from the later engine games wouldn't work), but for Colonel's Bequest the game would hang at the end of the intro sequence due to some sort of callback telling the script code the music had finished playing, which I identified and provided a patch for. Funny thing to reminisce on an afternoon 20 years ago, hacking on a driver to upgrade the sound in a game that was already by then ~14 years old which I'd played as a kid. Funnier still that only six months back or so I replayed this game again, but not before patching my ScummVM with a custom palette that I thought suited the game a little better than the default garish EGA colors..
