I have a Wii with the D2Pro chip. I haven't done any softmod what so ever (no homebrew channel etc.) since I don't wanna risk bricking my Wii. If I buy the retail New Super Mario Bros, will it work on my Wii? I have Wii firmware 4.1E now, I don't know if the game will require an update. I read somewhere that after playing retail NSMB something will happen to the Wii so that I can't play my back-up games. Is this true?
