A new world record speed run for Super Mario Bros. was recently set by a player named Darbian. This same player also held the previous record for finishing the NES classic in the fastest time possible. It took Darbian years to shave just half a second off his previous record. Now that he has topped himself, he is officially done with trying to set another record. Considering how this current world record speed run is nearly perfect, it’s entirely possible that we may never see anyone top the record either.

Darbian’s original record for beating the game was 4:57.427. The new record is 4:57.260. In order to achieve such a fast run, he made ample usage of the game’s warp pipes. Then, of course, is the muscle memory he has developed from years of doing this run. All of that, along with the “bullet bill glitch” that allowed Darbian to skip the castle walk at the end of the level, helped him shatter his previous record literally by milliseconds.

For this speed run, Darbian played the game on an NES console set up for streaming and also showed his heart rate, which was around 80 beats per minute for most of the run. When he entered World 8, it began to rise as he knew he was on the verge of besting his previous time. His heart rate maxed out at 172 bpm.

It’s a certainty that other runners will try to top Darbian’s time, but they’ll surely have a hard go of it. If it took years to shave half a second off the previous record, then other runners’ chances are looking to optimistic.
