I'm trying to mod a game (injecting VR), and to do that I need to edit globalgamemanagers and inject the supported VR devices in there. I would like to be able to do that through my own code. It seems like UABE is the only tool for that, and it isn't open source. I have no idea where to start with this. Is there any chance the source code for UABE could become available? Or that I could get a hint on how to edit this globalgamemanagers file myself?
