I haven't found a lot of information about this, is it not really handy? Do people usually just skip that level?

Is this for any% or no warps?

And yes, this is already found a while ago. Sorry. For any% people go to 7-1, then manipulate the game’s RAM using shell placement and a note block and a side clip in a pipe to warp to the end credits in 3 minutes.

Cool, saw some videos by Summoning Salt on YouTube, I didn't even know this was a thing before, but I think it's pretty interesting. I doubted very much I'd found anything new, and doubted even more it would be useful, but figured it couldn't hurt to post.

Summoning Salt is awesome. I watch him all the time.

Okey, im not sure if is used in 7-6 , but im pretty sure I look someone use it in 7-1 (i think that is 100% , obviusly not in Any% wrong warp lol) In all case, nice glitch!
