And this was the moment I must have gone truly insane. On a total whim, I decided to do a cover of the Battletoads Game Boy complete soundtrack - all 14 tracks of it - and finished within a few days. There was never a NES version of this game, and I always kind of wondered what this music would sound like in NSF.
It's a straightforward adaptation, though I decided not
to adapt the sequencing bugs audible in the original version. The original was also in stereo, and I considered doing left- and right-panned voices at only half loudness, but decided to give those full volume, and decided it sounded better.
I made three versions: One with VRC6 for sawtooth bass, one with 2A03 for triangle wave bass (though it loses the volume control), and a third one in Namco 163 using an instrument that simulates the Game Boy's slightly corrupted version of the triangle wave bass, to give a more authentic sound. That particular instrument was originally used by my friend Pongball when she composed the chiptune music for the independent game Cuckoo Castle ( http://gamejolt.com/games/cuckoo-castle/87063
