Very cool! I did something similar for the Game Boy Color recently - playing 18kHz ~7bit audio while also updating the screen at 60fps, using "hi-color" techniques where you change the color palette before each line is drawn. It was a ton of fun with a lot of problems like "aha, if I use this register for this value, it saves 2 extra cycles!". My code's here: https://github.com/ekimekim/gb_music_video https://github.com/ekimekim/gb_music_video, and you can get a finished demo rom (which doesn't actually use any of the graphics stuff due to lack of assets) here: https://ekimekim.itch.io/steamed-hams-but-it-plays-on-a-game-boy-color-audio-only https://ekimekim.itch.io/steamed-hams-but-it-plays-on-a-game... I should note that the technique I used for audio on the Gameboy was taken from this excellent video: http://tasvideos.org/5384S.html http://tasvideos.org/5384S.html
