the text was not an update but a warning that it found that you have a modchip so u need to upgrade yer modchip also.
The strange thing with me was I can play SMG on my PAL Wii, I did the disc swap trick, so I have no duplicate channels...BUT a few days ago it suddenly gave me that message "blabla...detected an unauthorized modification..blabla".... I was terrified! So I reset the console and tried again. Everything worked fine and I have had no problems since.
How can this be...having played SMG several times without problems and suddenly it gives me this message but after that everything is okay! Is my Wiikey buggy?? Or is Wiikey buggy in general?
