I’ve just discovered the truly awesome range of games offered for fantasy consoles on itch.io and I would love to play some of them on the Miyoo Mini. OnionOS seems to be able to emulate Pico8, but can anyone tell me what the methodology is?
I imagine that one would need the .PNG cartridges, but these are not always distributed, only binaries.
https://onionui.github.io/docs/emulators/pico-8 says pretty much everything else I would say. It's also worth noting that you can rename .p8 files to .png and they'll work the same. The advantage is that the .png file also functions as cover-art.
The default configuration of OnionOS uses the fake08core for PIC0-8 games. Its compatibility is good but not perfect. I believe it's possible to set-up the paid-for, official PICO-8 runtime, but I've never done it so I have no notes.
