The VR fork didn't work at all for me with the Quest 3 unless I was doing something wrong. None of the controls worked lol although I sorta was expecting it to not work considering how old the fork is and how new the Quest 3 is in comparison...upon revisiting this to try to get loaders to work on it I have decided that the dlls in the game are stripped which prevents mods that would easily add some things to it. Such as vr or other things.
Might play with the idea of unstripping it if I feel like learning that. I also downloaded the leftover abandoned vr version made by a fork team. It has some issues though such as having horrible lighting which could easily be fixed. Would take some time though so don't hold your breath.
Also, I'm pretty sure you can find unstripped DLLs on the KK discord. I've used them to install BepInEx plugins that let me control various things in the game
