I installed HB and Gamma for a friend and when loading some games with HD cables it throws a green screen. I have installed the same cIOS and such on my Wii. I have no green screen error on mine. Mine has been a bit of a testing ground for all of this so I don't know if there is an app or Cios installed on my Wii which I have missed on this Wii. I've installed DVDx, Gamma loader, Beta Loader, SoftChip, Starfall, and all needed IOS's above v3.2 firmware. I've tried to duplicate everything from one Wii to another with no luck. On the Wii causing a green screen error if I force Vid in the options for Gamma the game will run with no problems. On mine I don't have to do this, so there must be something I have forgotten to install. Does anyone have any ideas? I realize green screen errors are common with standard cables, but this is with HD cables and only happening on one system. Any help would be appreciated.
