Like, when I downloaded the patch from here, it seemed to be in a ".patch" format instead of a ".xdelta" format, even though the patch readme said to use an Xdelta patcher. None of the Xdelta patchers I've tried have accepted the patch file. I'm getting the error that says it's "not a VCDIFF input".

Does anyone have any advice on how to get this to work? The official site for the GCCX patch seems to be down, so I have no idea what else to do...

Come to think of it, the patch from this site seems to be calibrated for a "[ b ]" rom, or a bad dump. I wonder if it's because I'm using a clean rom?
