Tool-assisted speedrun

A Tool-Assisted Speedrun or TAS, also known as an emulated run or time attack, is a speed run created using emulators to optimise every last frame. They therefore invariably contain feats that are humanly impossible.

Constructing a TAS is more like animating a movie than playing a videogame, and requires much, much more patience than actual videogaming skill. Both TASs and real-time speed runs require concentration, dedication, planning, and far too much free time, but TASs are not listed on this wiki, and you can think of this as the videogaming equivalent of banning steroids. This wiki is about real play.
