I had my wiikey installed by a fairly experienced friend who has modded several consoles in the past so i think there shouldn't be any problems . Problem is I can't get wii to read udpate or settings disk. I have tried dvd+r, dvd-rw and dvd-r all differend brand and the -r was fairly expensive, maxell. the disks were burned with imgburner at 2X. I haven't tried any copied games as I can't see why it would read any other disks. My wii firmware is 2.1E does this matter?
