Have you ever beaten smb without warps?

Whoa, how did you get that pipe to take you to the warp zone in 4-2?

You can do the same thing in 8-4 to save a little time.
I do the same in 4-2 but in a different way. I make Mario get stuck on the blocks at the beginning of the stage and pushed far right, then I just continue to said pipe as normal and the trick works.
