During a month-long js13k gamejam warmup (July 2022) I spent some time learning the basics of making chiptunes. This was a bit of music I made in the final week of the warmup - which I thought turned out ok-ish - along with some friendly gameboy-style sheep. I used OpenMPT for the music (open source music tracker) and Gameboy Studio for the sheep part of the demo.
Both the song and sheep demo should be composed correctly to play on an actual gameboy as well, I stuck by the channel restrictions the gameboy hardware has for music/sfx. But I havent got the custom hardware required to test that (yet) 🐑
