Kosmic sets the fastest Super Mario Bros. speedrun of all time

Yesterday, speedrunner Kosmic broke the world record for the fastest completion of Super Mario Bros. Kosmic clocked in at an impressive 4:55.913, completing the game in the any% category. Previously, a record of 4:56.245 was held by somewes. Kosmic tied with somewes’ speedrun merely 30 minutes before eventually breaking the world record last night.

Visual proof, along with an overly joyous ending, is right here:

Such an achievement can only be accomplished through hours upon hours of practice. Despite being a run on any%, Kosmic studied Super Mario Bros. with precision, memorization, and steady hands. He completed the run with an original Nintendo Entertainment System and controller. Kosmic notes that this record took over 1,600 attempts.

According to the game’s TAS, or tool-assisted speedrun, it is possible to beat Super Mario Bros. in 4:54.03. This means, if a player’s input were 100% accurate and their control of Mario were perfect, a run of 4:54.03 could be possible. After Kosmic clears the run toward World 4-1 in the above video, he says aloud, “literally tied with the TAS.” He’s referring to the fact he did exactly what he needed to do, exactly how it needed to be done at that time. To do any better at that moment is impossible.

Kosmic told Press Association that he didn’t believe he’d break the world record during the run he was completing.

“Since this was the very first run I had on this pace, there was no way in my mind it was going to be the run,” he said. “That’s why I was cracking jokes the whole time. Even going into 8-3 I wasn’t that nervous, because there was just no way it was going to happen.

Kosmic has been speedrunning since 2011. A full list of current world-record holders for completion of Super Mario Bros. on any% can be found here. Congrats, Kosmic!
