After asking Arborelia for help on how to make MSU-1 packs, I was able to prepare a few tracks last night. I'll probably do an extra stream sometime this week to show it off.
If you don't know what an MSU-1 pack is: the MSU-1 is a theoretical chip for the SNES (which only exists in the context of emulation) that allows it to play high quality digital music. There are a bunch of packs over on Arborelia's MSU-1 page, where you can get some music packs and learn more about the whole thing.
