I have been installing Wiikeys and other mod chips in other consoles for a very long time, but this is the first time I have experienced an issue like this. My first installation of the D2C key went smoothly, and all the connections seem excellent. However the modded system will now only read backup discs, and will not under any circumstances read the original discs. I am baffled as to why. When installing the D2CKey I did not install the wire for the region override and did not set the jumpers specifically for any region. Could that be the issue? Has anybody else experienced this issue?
