A full TAS by iMathII and cstrakm, using the fastest known skips for every 150cc track, including the Extra (SNES) Cups. This one has a faster mid-run reset than iMathII's original video and trims a blank frame from the end, and also adds 2 frames to sync to SRAM generated by a verification file (Forum/Posts/531655).
A replacement 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
