BizHawk is a multi-system emulator designed for Tool-Assisted Speedruns (TAS). A regular "speedrun" is where a player tries to complete a game in the shortest amount of time possible, without using cheats. Tool-assisted speedruns use features only possible in emulation like slow-motion, frame-by-frame advance and save-states to create a series of controller key-presses, which makes the player look like they are insanely good at the game. Regular speedrunners often collaborate with TAS speedrunners to find the quickest ways of beating a game.


BizHawk has native support for emulating the following systems. This list isn't definitive as BizHawk also supports Libretro emulation cores.

  • Atari 2600, 7800 and Lynx
  • Nintendo NES, SNES and N64
  • Nintendo Gameboy (Color) and Gameboy Advance
  • Sega Master System, Game Gear, Genesis, and Saturn
  • Sony PlayStation and PSP
  • Various others like PC-Engine, Neo Geo Pocket (Color), etc.

Despite being designed for TAS, the developers of claim it is also an easy-to-use emulator for casual gaming. As with many multi-system emulators, BizHawk suffers from "Jack of all trades, master of none" syndrome. Meaning if you want the very best emulator for a particular system, BizHawk might not be the best choice, unless you're interested in TAS of course. But judge for yourself.
