A year or two ago I was charged with writing a "snes-like" mini-soundtrack. The tracks are on my other computer, so I'll have to upload them tomorrow (or Monday :s). Also, I'll upload a "SNES SountFont" courtesy of Setzer- (from VGMusic). It's incomplete, but contains a nice array of SNES sound samples (including the characteristic Final Fantasy VI string ensemble sample). I used the soundfont as a sound source for 3-4 MIDIs in that project I mentioned. Pongball (VGMusic/Omidia) currently has some samples of music she has written specifically for the soundfont:

He took a non-VG sequence of a Hiroki Kikuta piece that I made a MIDI sequence of and ... put it through a Secret of Mana soundfont that he had devised. Very clever stuff.
EDIT:
