I was with a friend thinking about making a Pico 8 handheld with A Raspberry PI, and a small screen, and some buttons and a battery, and we want to make it but we have no idea how, it would be cool to also have a teeny-tiny keyboard that we could use on it, we know for the software we can just download Pico 8 on Raspberry Pi OS and have it launch on startup, we could use spore for the games and thats why we need the keyboard. (except if there is a way to get an on screen keyboard that would work similar to those of PS4 and XBox) we want to specifically make it ourselves, and only for playing Pico 8 games. Any help?
