isn't the value in world 4 6?

So, yes, normally, that subroutine will check to see what kind of level Mario is in, however, by clipping through the pipe, you don’t parse that second scroll lock object, so the subroutine isn’t triggered.

I just tried this by hacking the pipe that normally would send you to the flagpole to send me a bit further back in the level to surpass the scroll object twice. the warp zone pipe still brought me to the minus world. So the object probably does not increment the value by 1, but instead set it to 1.

I’ve done tests where I have manually set the value to values like 08, and when hitting the object, it increments to 09. The other scroll lock object does set it to 04; when at 09, hitting that object set it to 04. The first one increments, the second sets.

Then it might reset during warps?

It does, after every death, or warp, or level load, the value resets to 0.

Then this will probably not work, since it's impossible to scroll back the screen.

Yes, as far as I can tell, although my theory that incrementing the value twice will send you to world 8 if you clip into the area where the warp pipes after having incremented it twice (this theory been proven through manual incrementation of the value through hacks), it is impossible to do so during regular gameplay, and thus the trick is (based on our current knowledge and testing of the game) impossible.

is thats posible it would actualy be faster doing world 6 and 7 instead of 2, 3 and the rest of 1 and of 4 tecnicaly 4 levels faster so like
