I covered the Scuttle Town theme from Shantae. I tried to get it as accurate as I could, and I think I did a pretty good job.
(For reference, here is the original. (If you're wondering why the drums sound different, it's because I was aiming to replicate the in-game version rather than the OST version.))
EDIT: Fixed a minor issue that affected the exported NSF.
EDIT 2: Fixed a minor instrumentation issue.
WOW that's impressive! I would have totally believed that came from the actual GBC game. To be 100% honest, I had no idea FamiTracker could do melodies from games over than NES.
