The world record for the fastest time to beat Super Mario Bros has been broken.
Speedrunner 'Blubbler' has beaten what was previously considered the fastest possible way to beat the game, which previously resulted in a world record of 4:58:09.
By using a recently discovered glitch and being able to pull it off during a speedrun however, Blubbler has been able to reduce that to a new record time of 4:57.69.
The glitch occurs at the end of World 8-2. By jumping on a Bullet Bill just as he hits the corner of the flagpole, Mario doesn't have to walk to the castle and the game accumulates the score instantly instead of waiting for him to get there.
You can see the full speedrun below. Congratulations to Blubbler!
