This is a sort of bs response, but it's possible to make a DLL to use with an injector that will load a different REZ file and force CrossFire to re-load a REZ file(therefore un-load a REZ and re-load a REZ in where the DLL was placed). Doing so can't get detected(until they do something about it). Also it should be possible to make an injector specifically for injecting REZ files into CrossFire. This is all I can think of. I'm not a coding genius, but that's my ideas.
~~Hope this may have even been the slightest of help
Can't wait for a flawless bypass btw xD
