Willis Gibson, 13, claims to have beaten Nintendo's classic video game.
Gibson, who took 38 minutes to win, posted the video on his YouTube channel the moment he reached the 157th level.
The game had crashed when he reached the level.
After the 38-minute run, the screen crashes after he wins.
"When I started playing this game I never expected to ever crash the game, or beat it," Gibson wrote on his YouTube channel as quoted by BBC.
