I have pico 8 up and running on my pi2. Everything seems fine except every special key (alt, shift, page-up, etc..) generates a space. Or at least something that looks like a space. This only happens in the console, the editor is fine, and works as expected. The keyboard is a generic en-usa usb keyboard, that works as expected everywhere else in the pi. My distribution is retro-pi current and up to date.
