I play enough with PICO-8 and VOX on my PC that I should get a dedicated Pi just for this! It's amazing how much fun it is playing other people's games, and starting to work on your own. Great to teach little ones programming.
Slightly off-topic, but can someone confirm if it's actually bad/electrically dangerous to run composite video through RCA audio cables? It's visible in the first image.
"Proper" RCA audio cables are 75 ohm impedance and can carry composite video just fine. Lower quality cables will most likely carry the video but you may see degraded quality. It is not electrically dangerous.
I haven't even cracked open the sprite editor or tracker yet but a dedicated PICO-8 box would be awesome to have in the living room as a sort of coffee table computer.
