A full TAS by author iMathII, using the fastest known skips (except for two suboptimal tracks) for every 150cc track, including the Extra (SNES) Cups. This one has a fast mid-run reset.
The original input file for https://tasvideos.org/9292S . Uses BizHawk 2.9.1, mGBA core. Not converted/tested in GBAHawk but it'd be a good idea.
Game version: Mario Kart Advance (Japan).gba
