In the original ROM, 8-4 can do wrong warp through the first pipe Here's a shortcut that saves a lot of time 8-4 speed pass should use practice rom, but soon we found the problem The practice rom cannot perform wrong warp I don't know what to do, can anyone help me?

Maybe we can use the original ROM to speedrun 8-4.

Also split 8-4iL into two categories, one is '8-4iL', and the other is '8-4iL No Wrong Warp'.
