i'm trying to play the original rockband 2 game on my wii (wiikey 1.9g and 3.1U firmware). however, when i insert the game disk it asks me to update. so my questions are: 1. if i update, will it update to 3.4U? 2. is my understanding correct that the 3.4 firmware only affects homebrew channel and wads? so if i dont use homebrew or wads, can i still play all my back up games? will it affect my wiikey? i hope somebody can answer my queries..... thanks in advance, guys!
