Pokemon fan who might be a robot in a convincing meat suit completes 107-hour challenge playing 100 versions of Sapphire at the same time

Pokemon players have come up with some truly weird and wonderful ways of playing the beloved RPG series over the years, from the popular permadeath "nuzlocke" challenges to even more brutal Kaizo Ironmon runs. Now, though, one player has managed to complete one of the most bizarre challenges we've ever seen by playing through the Game Boy Advance classic Pokemon Sapphire 100 times simultaneously.

Rather than running 100 copies of the game in front of them at the same time, YouTuber Rylockes decides to make the challenge even more complex. Instead, they always have two files playing at once, both using the same controller so that making progress in one potentially meant walking into walls in the other. On top of that, every three minutes, these two games were randomly swapped for another of the 98 files. This meant that Rylockes was constantly being thrown between the different saves, and as things progressed, it became harder and harder to discern how much progress had been made in the games they were dropped into. 

This wasn't a problem at the very start of the challenge, as Rylockes kept getting given two files that hadn't been started on, allowing them to progress through both smoothly using the exact same inputs. It only took half an hour for this to be thrown into disarray though, as one of the files shuffled back to one that'd already been started on – something that quickly became the norm from then on.

Split-second lapses in focus could be catastrophic, with some of the YouTuber's many Mudkips accidentally forgetting their most valuable moves after being overwritten in a frenzied button mash. There was also the constant threat of the games being shuffled in the middle of something important, such as a Pokemon
