Tool-Assisted Speedrun, n. Refers to a speedrun of a video game, using an emulator's slowdown and rewind functions to reach an inhuman time. TASes do not use cheats (though glitches are fair game), meaning that in theory, anyone could replicate a TAS on a real console, though no human has the reflexes to do so.
Hey, did you check out that awesome TAS of Super Mario Bros.?
