hello,
I just received my PiBoy from ExperimentalPi (it's running retropie) and, although Pico-8 is working fine with an external usb keyboard, I can't succeed in mapping/registering the integrated joypad and buttons with Pico-8.
did anyone figure it out?
thanks a grand

See if the information here can help you: https://pico-8.fandom.com/wiki/Controllers

I'll have a look, thank you for the tip merwok !
