These undersung athletes are now just 0.1 seconds away from completing a perfect run of Super Mario Bros., as detailed in a new video from former SMB world record holder Kosmic. LeKukie set a brand new world record run for Super Mario Bros. on June 2 this year, completing the game in 4:54:365. The first was equalling the world record on Super Mario Bros., but then things went wrong again. And then just a couple of days later he did it, setting the current world record. LeKukie’s record left just six possible frames of improvement on 8-4, following a perfect run of the rest of the game.
