I think an Amiga version of this would be great, especially using MOD files. Most of the limitations I had writing Shredz64 all stemmed from SID files. Not that I don't love chiptunes, but SIDs are a royal pain to work with for a number of reasons, all stemming from the fact that they're machine code as opposed to music data. They have to load in at a certain address, which means that a lot of them are unusable if they load in at the wrong address (e.g. on top of the game code). Also, since they have their own player, you can't really silence the sid while its playing and play a "misplay" note.
Tracker music would be awesome as its actual music data and not machine code, and would overcome all these issues.
