Hello, I'm looking to start running 'Super Mario Bros. 3' Any % (No Wrong Warp). It looks like there is a wall clip needed in Bowsers' Castle to get a time close to world record speed.

The clip in question happens at 10:57

If someone could clarify how to do this, I would greatly appreciate it.

Thanks.

I think you crouch jump up there and stop holding down, but i dont run this game.

Luckily, the link you provided is from a runner that uses input display. It could be worth taking a closer look at it to study and figure out the details that way.

I saw the input display, but he goes so fast it's hard to decipher what buttons are being pressed. I imagine jump is being used, but does it have to be mashed? What about B? What about the D-Pad?

Ok so as far as I know, it works like SMB1 and luckily, I know some stuff about it lol. So basically you have to crouch jump in the corner and try to hit the bottom of the block (the wall is made of multiple blocks). Doing so makes Mario hit a pixel where he can stand on for 1 frame. Using this pixel you can either jump or just let mario clip since it uncrouches Mario (so down hold Down when you do it). So the inputs aren't hard, you crouch jump in the corner and hope you get the right pixel. If you want to see in slow mo, put the video on .25x speed or use the . and , to advance frame by frame
