From Playdate Community Wiki
A port of the Peanut-GB Gameboy emulator for Playdate. Peanut-GB is a header-only C Gameboy emulator created by deltabeard. I have tried to optimize as much as I could for Playdate, but most games still only run at 20-30 fps. Because the Gameboy ran at 60 fps, this means games will feel like you are playing at half speed or slower. This port has working audio, a rom picker, and save support (not save states).
