In my years writing about games for Ars, I've covered my fair share of surprising glitches, long-secret codes, arbitrary code execution tricks, and deeply hidden content buried within some classic games and hardware. But none of that prepared me for the above Twitch video clip I saw this morning, showing a fleet of flying Arwings from Star Fox 64 invading the world of Ocarina of Time to attack Link. It's the kind of scene you'd expect to see only in a fan-made animation or in a ROM hack of the type Nintendo is so fond of taking down from the Internet.
