[TAS] SNES Mega Man X & Mega Man X2 & Mega Man X3 “300%“ by agwawaf in 43:

This is a tool-assisted speedrun. For more information, see In the latest in silly ideas turned into inspirations for our ever-dedicated TASers, this movie takes one controller and wires it into three SNES emulators at once; the same input is used to play 3 games simultaneously with one controller. There are also animations constructed with spare controllers during this movie. This movie beats the first three Mega Man X games with 100% completion each (an improvement on its predecessor, which beat only the first two games and without 100% completion). If you like this movie, there are other movies that beat four games with one controller! Note: There might be a visual anomaly during the battle with Serges in X 2. This is an emulator bug relating to the Cx4 chip used in the Mega Man X 2 cartridge.
