PICO-8 Station is a modified JELOS firmware which makes your RGB30 into a dedicated handheld device can only run PICO-8.
You may achieve this by leveraging boot-to-game feature from some OSes. But I found it fun by tweaking the firmware and “downgrading” the device to a dedicated PICO-8 handheld console this way.
Only works with official PICO-8 binaries. If you don’t own a copy, check PICO-8 Fantasy Console (lexaloffle.com) to get one.
