Hacking Rock Band question

[WilliamAlanBaile]

Since Rock Band can use the instruments that came with Guitar Hero World Tour, if I have played the official Guitar Hero game does that mean the ios's that are needed are already installed? I don't want to even mess with downgrading my Wii from 3.3 v1 so I can install ios's.

If you have already installed cIOS36_r7 (IOS249) you can upgrade and downgrade without any problem, but you could also just try the game and tell us if it worked or it needed any IOS, I've done what already said, 3.4-->3.2 so I have all of the IOS in existence...!!!

Guitar hero instruments do not need ios 37. Only USB instruments need IOS 37.
So to use the mic with Rock Band you need ios 37.
