Is there any particular tracker to use to create snes music Open MPT is great but I can't figure out how to convert the result into the SPC format for the SNES. All help appreciated.
You have to look into SNES focused tools that can convert certain types of mod music/tracker files into something that can be played back on the SNES. Any general tracker program is not going to have any way to output a SPC file. There are atleast a couple SNES projects out there related to converting and playing MOD type music in SNES programs. One I think is SNESMOD, and I want to say there was another but I can't think of its name.
Shiru's SNESGSS is the only one I know.
SNESMOD can be found here:
