He said he holds "right" the entire time he does this. I find it odd because I've never done this. I know that holding "left" right when you reach a wall usually sucks you into it, however, I've never seen someone go any distance into the wall while holding "right." This is a bit interesting. I always thought that walljumps were always a 1 frame trick. But I guess if you position right, you can have 2 frames to get it? I'm testing on emulator, and I can't seem to mimic Kosmic's 8-4 walljump. Really, I'm just curious how he could have gotten into the wall if he was holding "right" the entire time. Maybe the positioning has to be perfect?
In order to perform a wall jump you must, aside from being at the same y-pixel as the wall block you're landing on, be at least 1 pixel inside the wall. In this case it means having an x-pixel position of at least 115 to have frame to do it, or 116 to have 2 frames to do the wall jump. The wall collision detection routine is called when you reach at least that 115 x-pos and pushes you back 1 pixel / frame - starting immediately, meaning that if you get to x-pos 115 you won't be able to wall jump at all since you're directly pulled back to 114. You move at a speed of 2.5 pixels / frame so in order to reach that 116 x-pos you must, on the frame before hitting the wall, have an x-pos of at least 114 pixels and 128 subpixels (which would for a fraction of a frame put you at x-pos 117 but later at the same frame pull you back to 116). Here's an fm2 of it: http://dehacked.2y.net/microstorage.php/info/934806167/Super%20Mario%20Bros%20%28JU%29%20%28PRG%200%29walljump.fm2

How can he be facing backwards, but walljump facing to the right? Ive never seen this happen, but he says it happens frequently.
A short answer: Normally you need at least 1 pixel inside the wall to do a walljump, while in this case you need 2, which requires X-speed > 32 before hitting the wall. With the X-speed of 40 (full-running speed), this thing does happen frequently whenever you are deep (2 pixels) inside the wall, holding right, and happening to press jump 1 frame later. With the same way, you can also face right before you hit the wall , and face left after the walljump. If you've seen my SMB "lowest score 500" run, you may also find it possible to walk for a few frames after hitting the wall and do a walljump.

I believe the current warp run is perfect. I am going to think about and test every single theory I can think of for a chance to improve this. I'm just very curious. Thinking through it, with all my knowledge of the game, I can't think of anything that would even have a chance of working for most every stage. If the run is improvable, I believe the improvement is hiding in 4-2. I think a 21 frame rule could potentially be squeezed out here. There are a variety of methods to move Mario forward on the screen, and a combination of methods may work for a faster time into the pipe.

I believe the easier improvements would come from 8-4 (and 8-2 if you get lucky) as I mentioned on Youtube. I don't think there would be a quicker way to push Mario forward on the screen unless you'd try something considered extremely hard like going through the wall on console runs. You have to hit the wall at least 2 times before the pipe, and as far as I know, your solution is one of the fastest in theory.

This game has a 21st frame rule. You also need to optimise subpixels to get as fast as HappyLee. And I think a pacifist run wouldn't get published, so don't try to optimise your run.

That's OK, keep fighting, and one day you would make it. :)

Wait, wouldn't a pacifist run basically be HappyLee's "warped" run just with all the enemy stomping removed? Does that really warrant a new category?

It's not a bad category idea for a novice TASer to try out in order to practice optimized TASing. Very little chance that it merits publication, though.

http://www.youtube.com/watch?v=FgDqwa_pzmg Sorry if this is too off topic, but in this video at 6:01 and 6:20 he traps a koopa in a block and has it go to the end of the stage without falling or hitting any blocks. Does anyone here happen to know or have a detailed explanation of how this works?

Do you know also, when you hit box with Mario, he hit not with his head, but with hand?

Also, when you hit the flagpole, he does not slide down, but rather he climbs down?
So yea, how's it going? Currently TASing: Nothing
