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.
Lode Runner (NES) might be okay. Not multiplayer, but it’s got nice low-stakes puzzling gameplay.
Edutainment games are a bit few and far between on consoles - Donkey Kong Jr. Math springs to mind, but it’s remarkably dry for a Nintendo game.
