the Super Mario Bros. The speedrunning community is constantly looking for new ways to push the state of the art forward, and one player has just accomplished what was once considered an impossible feat… at least for a human.

In 2018, sprinter HappyLee used a computer aid to demonstrate a new method to remove some frames of Super Mario Bros. World Cup 4-2. It involved using precise inputs to make Mario miss (slash) through a row of blocks, the top row, near the start of the level, pushing him to the right faster than ever before. It then required a super-precise jump into a warp tube. The sprinting community had assumed that a complete and perfect 4-2 run using this “top clip” trick could never be accomplished by human means due to the great precision required and, fortunately, has since discovered alternative methods and more. easy to maximize min-maxing. 4-2. But on Monday, a sprinter named Tole managed to pull off the “top clip” 4-2 trick without the help of a computer.

Here’s what’s happening: Through precise inputs, Tole had Luigi go through the corner of the top block, touching the ground inside the wall for one square, and then jumping from inside the wall. Based on HappyLee’s original discovery, this maneuver should remove three frames from the race. This doesn’t sound like much, but it’s particularly important in the 4-2 world because of a Super Mario Bros. concept called framework rules.

Framework rules are a somewhat esoteric concept. In Super Mario Bros.the program only check level completion every 21 frames. So if you enter a level ending castle right after the most recent check, you will have to wait up to 20 frames for the next level to start.

a sprinter Kindly explain the framework rule. using a bus analogy. Imagine that the castle at the end of each Super Mario Bros. level is a bus stop. The bus only arrives (the game records the player beating the level) once every 21 frames (around 0.35 seconds). So to set world records on some levels, you can’t be faster for a small amount of time; you have to be fast enough to catch the previous “bus” that leaves for the other world.

Catching the first possible bus in level 4-2, as first demonstrated using computer-aided walkthroughs, is sometimes referred to as “Lightning 4-2”. That’s why HappyLee’s computer aided tricks, in which Mario saves a few frames by going through the top block in level 4-2, caused a sensation: it was another way for racers to get around the frame rule and theoretically catch the first bus. Current Super Mario Bros. Niftski sprint champion used a similar trick on his new world record this past week. The difference was that he jumped under the block and ran inside the wall, a completely different and much more practical method for humans to use in actual racing.

Kotaku reached out to Tole, but did not receive any comment at the time of publication.

Since there are easier Lightning 4-2 methods out there, the Lightning 4-2 Tole “top clip” that was pulled is probably just for show. But speedrunners who understood the incredible difficulty at stake here were impressed by Tole’s feat. “Holy cow, I doubted the feasibility of this method for years and you nailed it,” said one commenter. “THIS IS CRAZY SHIT,” wrote another, emphasis his.
