Ahh, that's interesting. ElSemi says that a few Model 3 games seem to use FM as well, so maybe we can get something going there.

I wouldn't expect a lot of DC games to use sequenced music, but then I didn't expect PS2 games to use it either and it turns out to have been rather popular :-) Also, the Skies of Arcadia test rip is just 1 song. As one of the 15 people who bought and loved that game I'd really like a full soundtrack rip.
