I'm really sorry for posting this here but I was wondering if someone could just tell me yes or no to whether I should do a system update? The wii is asking me to do so or else I won't be able to play a game of mine. It also said that updating could cause the wii to become unusable if I had modified it before. I have a Wiikey 2 in the Wii... Can I update? I would REALLY like to play this game.. Thanks!!
