Hi, I bought my US Version Wii from a shop and they claimed the WiiKey is installed inside already. Now I am having doubts as I have burned TDK 4.7GB DVD-R with games and it is unable to read my burnt disks. Is there a WiiKey symbol when I boot up my Wii? Or does it all look the same? I'm having doubts that my Wii is even modded now and the shop swindled me! Help!
