1 Key

1 Key is the current evolution of the any% category which involves skipping Bowser in the Dark World, the first Bowser level, by using a glitch that makes the key obtained from that fight unnecessary. The central glitch was discovered in mid-2015, and was revealed to the public when sonicpacker uploaded a video showcasing it. The strat involves using PU movement to navigate in front of the door under the moat with 0 stars, exploiting the facts that PUs have no water, and that the door-opening action takes precedence over entering the water within the course of a frame. The first ever TAS of 1 Key was released on September 29th, 2016 with a time of 4’21”67. This came more than a year after the original reveal, which was due to the fact that getting QPU speed requires visiting Vanish Cap under the Moat to BLJ on an elevator and visiting VCutM originally required 10 stars to get the Wing Cap for Hyperspeed Flying, until a BLJ on the castle grounds was found that sufficed. The current record stands at 4’21”2, though 1 frame has since been saved in Bowser in the Fire Sea. Since this skip saves the time normally required for the first Bowser level, this TAS holds the world record for the fastest known completion of Super Mario 64.
