Hi I had some problems with Guitar Hero 6. I have a Wii with Wiikey 1 and software modded. Wii Firmware is 4.3. (Updated 30 Oct 2010) When I insert the Guitar Hero 6 backup disc it forces me to update The Wii. I had tried to run it with NeoGamma R9 beta 47 without updating the firmware but it gave me a black screen and does not run. If I update the Wii with the Guitar Hero 6 it will run and I can play with no problems (must be the Wiikey working there). But after updating it, it removes the custom cIOS. So if I ran sciifii I can hack again the Wii. Does anybody know which Wii update installs Guitar Hero 6? or it is some kind of validation that the game does to check that the Wii is not hacked? Thanks.
