I completely agree with you Andrew, even though you discovered wrong warp for speedruns, this method might have been discovered in like the 80s or 90s.

I already knew about the wall glitch, this can be another way to do the walljump easily on 8-4, but there isn't really an another use for it if your going for sub-5 minutes. Plus, that will lose time anyway, so it really is only used for people who want to do the wrong warp easily. Still a good glitch though, it's just that it won't be helpful on WR attempts, or sub-5 attempts.
