Copyright claims are the stuff of nightmares for content creators on YouTube. For speedrunners of the NES classic Super Mario Bros., their videos showing off personal bests and world records were accidentally targeted by just such a claim.

Super Mario Bros. is a game that many still play to this day, as it is iconic, and fans praise it for providing the perfect video game tutorial with the well-traversed 1-1 stage. While countless casual gamers enjoy it, the game has also been taken up by speedrunners, whose only goal is to beat the game as quickly as possible. It has been so thoroughly optimized that there are only 4 tenths of a second between the world record and second place in the Warpless category (completing all levels of the game).

That world record run of 18:59.856, by runner Kosmic, caught the attention of Guinness World Records, recognizing it as the fastest time for the Warpless category. The organization wanted to put Kosmic's video of the run up on its own YouTube channel, and when it did, it triggered a wave of copyright claims on a number of Super Mario Bros. speedruns, including Kosmic's original video of the run. After several runners brought this to their attention, Guinness retracted the claims, calling them an automated glitch.

Super Mario Bros. continues to be popular to speedrun with the record for the Any% category having a tenth shaved off just recently. Often thought to be fully optimized, speedrunners continue to find small exploits that can save time in the game.

After discovering the automated claim exploit, this erroneous copyright claim was reversed in record time, to the relief of Super Mario Bros. speedrunners everywhere.
