>>712419302 (OP)A cosmic ray may have hit the Donkey Kong arcade machine at the exact moment to make the screen glitch like that, a similar thing can happen in Mario 64 when cosmic rays hit the console that once made a speedrun seem like the player was cheating. It was confirmed in court by an Electrical Engineering professor that it was entirely possible for the glitch to make it appear he used MAME when in fact he didn't even without any cosmic rays, however.
