Suggestion: Android Support
Currently, AFAIK, the only two ways to play Pico-8 games on Android is the P8 Player app, which doesn't support controllers and has input delay, and Retro8 on Retroarch, which is so unfinished even Celeste runs with graphical and sound glitches. I know that it would be possible to run Fake-08 via Citra to play Pico-8 games, but it would probably be better to run the app directly on Android rather than running an emulator within an emulator. Hopefully, this is possible.
