I'm currently working on rewriting the Gameboy audio engine for Teensy's audio library. Right now it is incomplete, missing a few things such as pitch sweep, but I have recorded a video of Pokemon music playing on it. End goal is to make a GBS player for all gameboy soundtracks, but I'm having the engine accessed from IO ports like the original. https://twitter.com/FroggestSpirit/s...084324354?s=19
