i've done 1-2 without releasing the run button but when i get a full block inside the pipe and try to walk/run it pushes me away. Can someone send the inputs in text and not in video? Thanks.

What's you're pb? You really shouldn't be going for that clip until you go for 4:55 attempts. So if your pb isn't near there, you don't have to do that clip.

I forgot to say its a TAS. For now my best tas is 4:56.3

These are 2 helpful resources. The first is a thread I posted a few days ago: https://www.speedrun.com/smb1/thread/n5n17 And the second is this video by marc: https://www.youtube.com/watch?reload=9&v=z8LnyLmzwqU What you want to do is to go about one frame from falling off of the 2nd row of platforms (Specifically the top one) and do a one frame jump. Then, only hold R from now on. One frame before you start walking press R + L, do a one frame jump, and get half-way thru the block, and press left. From then on, refer to the guide by marc I linked before. The most useful resource is in tasvideos,org, which I always refer to based on how useful it is. Here is the link: http://tasvideos.org/GameResources/NES/SuperMarioBros.html#GoingThroughBricks After TASing for a year, I am able to clip into any 2 block high pipe. Please do everything I have said, and also experiment with subpixels. You really want to do this, it will help SO much.

And if the setup I provided was too complex, please just use the one that marc shows, it is the method I started off with.

Thank yuo! Probably the problem is that i press left for too long.

Probably. Or, you jump at the begging of the level too early.

i just got it 2 times and im working to get a 4:55 tas.

Nice! Maybe one day you can beat my TAS of 4:54.8 hahaha

my worst level is 8-4, i have to get better fast accel/walljump

oof i just finished it and was 1 frame away from 4:55

@erenjake

show us the proof

@Lusonice2021 do you honestly think anybody need to show proof for a TAS. Anybody can make a TAS, ok.

@Lusonice2021 its not a speedrun its a tas.
