Speedrunners 0.1s from First-Ever 'Perfect' Super Mario Bros. Run

Kosmic, a Super Mario Bros. speedrunner and former world-record holder, released a video showing players are now 0.1 seconds away from achieving the first-ever perfect playthrough of the game. A perfect playthrough would meet the game's theoretical minimum completion time and mark a milestone for NES speedrunning. The tiny remaining gap means a sub-0.1-second improvement or frame-by-frame optimization is needed to claim the feat.

• Kosmic published a new video demonstrating current best runs sit within 0.1 seconds of a perfect Super Mario Bros. completion.
• Kosmic previously held the world record for the fastest Super Mario Bros. completion.
• A perfect playthrough would be the first time any player reaches the game's theoretical minimum completion time.
• The remaining margin to a perfect run is 0.1 seconds, requiring sub-second improvements to achieve the milestone.
