It's possible to remake the game to the OG version? I want to make the any% run, but I can't cause they fixed many things

No, I don't think so. If I were you, I would find a new glitch. If you can name off the glitches that are patched, I could be able to help you. On the other hand, you are better off doing a Glitchless%/100% speedrun, since nobody has yet done it. I don't know if this works, but maybe setting your PC to an earlier date. I'm not sure if that'll work. Sorry if I couldn't help you. That's all I got.

If you have the game, then you could try downgrading it through Steam for the time being.
