If you enter System Settings, does your version say 99.99.99?I have cbhc installed, I read that I couldn't but is it possible to run another CFW over it? Also I tried the Sig Patch thing aswell, I downloaded the one from the homebrew store but it didn't change anything.I compiled it once using the NUPacker (or whatever its called), I also tried it with the gui version that CrisMod put in earlier, but that didn't work either. The version I'm using is the North America WiiU, and I installed GTA3 from steam. Any ideas on what to look at next, or any photos I could post? Sorry for bothering you with this.
If not, make sure to set CBHC to boot into System Menu.
