Any solution for this? I tried to make a music, but I need the original music from the nsf.
An NSF is a computer program to produce sound. Unless the sound engine is familiar (and documented at romhacking.net), you'd have to disassemble the program and document its music sequence data format before you can write a converter. Or you could emulate it, log writes to audio registers, and try to discern MIDI data from the sequence of volume/pitch data over time.
