I have an old Raspberry Pi 1 (!) still going strong with Batocera Linux running NES, SNES and Mega Drive (Genesis) emulators.
I’m looking for easy multiplayer games that can be played with a 5yo. Non violent and ideally co-op, bonus points if somewhat educational.
“Toejam and Earl: Panic on Funkotron” (Genesis) has a very well designed “little kid mode” in the options, and it’s still really fun.
