1 Key: Difference between revisions

'''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, known as '''Moat Door Skip''' or '''MDS''' was discovered in mid-2015, and was revealed to the public when [https://www.youtube.com/channel/UCMmU0XaR0coor7dtJkEAh4A sonicpacker] uploaded a video showcasing it<ref>https://youtu.be/v5o_9XKmAfE</ref>. 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.

==Reason for delay of full run==

The first ever TAS of 1 Key was released on September 29th, 2016 with a time of 4’21”67<ref>Original TAS: http://youtu.be/j5j6l9ULxmI</ref>. This came more than a year after the original reveal. This was due to the fact that getting QPU speed requires visiting [[Vanish Cap under the Moat]] to [[Backwards_Long_Jump#Elevator_BLJ|BLJ on an elevator]]. Visiting VCutM without draining the moat originally required 10 stars to get the [[Wing Cap]] for [[Hyperspeed Flying]], which was slower than just getting 8 stars, visiting the basement, and draining the moat normally. Therefore, it would be useless to do this trick. Later, however, a BLJ on the [[castle grounds]] was found that sufficed to enter VCutM.  

Unlike all other categories such as [[120 Star]], [[70 Star]], [[50 Star]], [[31 Star]], [[16 Star]], [[1 Star]], and [[0 Star]], the 1 Key run is optimally performed on the [[Super Mario 64#Japanese|Japanese version]] of the game instead of the [[Super Mario 64#English|US version]]. This is because [[Peach]] does not narrate her dialogue in the Japanese version, saving time, but in-game text takes longer. Because the 1 Key run skips the [[Bowser in the Dark World]] text, the lack of narration is more significant than the longer text. Therefore, this run is ''not'' performed on the Japanese version because of version-exclusive glitches. It is performed on the Japanese version because the introduction is faster.

First, Mario performs a [[Backwards Long Jump#Slope BLJ|slope BLJ]] to gain speed in the castle grounds. Once Mario's [[intended next position]] is in the [[ceiling]] under the bridge, he continues BLJing, but it acts like a [[Backwards Long Jump#Low Ceiling BLJ|low ceiling BLJ]] instead. Since the height of a jump is proportional to Mario's speed, Mario's negative speed allows him to jump downward, past the grate, and into VCutM.

Mario quickly falls down to the elevators. He then sets the camera to [[Fixed Cam]] to avoid [[PU#Floating point truncation crash|a crash on console]]. Mario BLJs in order to get QPU speed (enough speed to perform [[PU#Travel and movement|PU movement]]). Then, he jumps to instantly die. Because he spawns in water, he keeps his [[sliding speed]]. Then, by pressing Z to slide and C^ to conserve speed, Mario conserves his QPU speed into the castle grounds. He then navigates to the moat door. Because there is no water in PUs, it takes a frame for the game to realize that the door should be unopenable once Mario returns to the main map. By then it is too late, though, as Mario has already opened the door (from behind).

Mario traverses the beginning of the level, using the [[hanging-ceiling upwarp]] glitch to pass the pole. He then performs an Elevator BLJ to gain QPU speed. Then, Mario travels through a PU and performs an [[Overflow Jump]], making use of high negative vertical speed to snap to the next highest point in the main map, entering the Bowser fight.

Mario uses a [[Glitchy Ledge Grab]] to quickly get up the first set of stairs. Although it is not visible on camera, Mario then performs a Side BLJ to gain speed. He then clips through the 50 Star door. Mario then performs Clock Punch, described here (scroll down)<ref>http://tasvideos.org/5237S.html</ref>. He then uses wall kicks to navigate past the [[Endless Stairs]] and into [[Bowser in the Sky]].
