This incredible clip comes courtesy of Speed Demos Archive, a site dedicated to collecting the fastest completion times of your favorite games. This speed run is for one my all time faves, Super Mario World for the SNES. This clip was not made using a special emulator or any cheats/hacks, just one man's skill pushed to the limits. His name is Adam Sweeney, on the Speed Demo site he recalls this being his fifth speed run...his penultimate effort! Sit back, watch, and envy some truly hardcore skills at work.
