I found this nifty tool while looking for a quick way to export channels from an nsf:
drag a AY, GBS, GYM, NSF/NSFE, SAP, SPC, or VGM/VGZ file onto the exe (ldont double click, actually drag your music file onto the thing you would normally double click), pick the track number, and boom you get you wavs for each track immediately.
Ive been using audio overload and outputting each channel one by one and it takes fucking foreverrrrrrr. This is way better! More in-depth arrangements coming soon, hopefully!
I've only tested this myself with NSF, but it worked perfectly and I had to run to tell you guys.
OKAY HERE'S ALL THE STUFF IT SUPPORTS
- Game Boy (*.gbs)
- NES (*.nsf/*.nsfe) [including VRC6, VRC7, Namco 106, MMC5, FME-7, and FDS expansion audio]
- Super Nintendo (*.spc)
- ZX Spectrum/Amstrad CPC (*.ay)
- Master System/Genesis (*.vgm/*.gym)
- Atari (*.sap)
- TG-16/PC Engine (*.hes)
- MSX (*.kss)
It uses the Game Music Emu library to run everything, which says it supports "MSX/ Other Z80", but I dont know what Other Z80 would be?
