If you have found any ways to use the door glitch in a run, post about it here. Additionally, if you have gotten the glitch to work on any of the HD versions please let us know!
I so far haven't found any good ways to use it besides skipping the 4-1 Queen's grail trap in 4-1. This can be done, as far as I know, on Gamecube, Wii, and PS2 (It might be able to be done on PS '07, don't know for sure though). Some thoughts I had were the second gate in the 5-2 hallway with the 2 Regenerators, the garage door next to the bulldozer in 5-2, and the gate to the Red Zealot room in 3-1 right after the water hall. None of these have worked. Brainstorming will yield the best results, though, and I am happy to try anything people suggest.
Me and pitted searched a bit for it, and i came with that thinking: That glitch only works with doors that can open and close (regular doors). So clipping through stuff is impossible unless it's a door. I may be wrong though. It would be amazing to skip any of the stuff you mentionned.
