It is not possible to enter the Minus World from either of the Warp Zones in World 4-2. The other two pipes in that Warp Zone are blank and registered as '36' (the number used for blank tiles in the game), causing the game to lead to World 36 when the player enters the world, hence the Minus World. The reason the middle pipe leads to World 5-1 is that the game is loading data from the World 4-2 over-the-top Warp Zone (not the one above the vine) that has only one pipe to World 5-1, and it does not realize that the player is in the World 1-2 Warp Zone until the room is completely loaded, i.e., the brick wall becomes visible. (This has a practical use, however, as it advances the player further than the normal Warp Zone would, although it is not used in speedruns as it skips past World 4-2, which has a Warp Zone leading to World 8.) If the player makes the brick wall on the far right visible (where the 'Welcome to Warp Zone!' message appears), the Warp Zone will be correctly loaded and the glitch will end. If he goes in the pipe in the middle, it will bring him to World 5-1. If he enters the pipe to the far left or far right, he will find himself in the Minus World. If everything is done properly, Mario will see the three pipes in front of him from the Warp Zone. This should glitch the game, allowing Mario to get through the pipe and wall, but doing it this way is potentially more difficult and time-intensive. He does not have to duck as he can try to hit the bottom left portion of the block (without actually destroying the block). He should move to the far left end of the pipe and jump to the right. Īnother method of reaching the Minus World involves Mario breaking two blocks on the ceiling, leaving the one on the far right. If not even one pixel of the pipe is showing, Mario will be trapped until the timer runs out. If this is done correctly, he will automatically move through the pipe (without the screen moving) and then through the wall and into the warp room. It may take the player several tries, for Mario must land in an exact spot on the pipe in order to travel through it. While in the air, the player should move right, so that when Mario (or Luigi) is about to come back down, he should be just under the ceiling next within this moment. Then, they should move to the far left end of the pipe, then duck while facing left. The player can get to the Minus World by going to World 1-2 and standing on the pipe that leads to the Goal Pole at the end of the level.
