Im curious on why it says that 5-s nomo is impossible because you can still do the oob to get to the elevator that is loaded

I would like to know the exact lineup for getting the skip on the first room of 0-4. An image would be helpful !

Idk how to replicate it or if it is useful

Is there any way to do the 6-1 clip at the beginning of the level consistently as it seems to not work most of the time.

How do I do the 7-1 oob?
