Herro, here's a VRC6 cover of a keygen song by Dubmood. Most of the info is on the Youtube video below, but I spent about 2-3 hours making this. Also, figuring out rapidly changing duty cycles are a pain in the ass, lol.
Keygen stuff translates pretty well to VRC6 considering how most keygen songs are considered chiptune anyway, lmao.
EDIT: Updated the ftm and nsf after realizing I forgot something in the frame set 4 for triangle, lmao. It wasn't noticeable in the Youtube or 8bc, but it was really obvious when you split the channels, lol. Should be fine now though.
Haha that's pretty neat. You really succeeded in capturing that very peculiar keygen song feel (present even in tunes not originally designed as keygen tunes).
