Alright, so i have a USA/NTSC Wii, and I bought an authentic wiikey, i know its real because it has the hologram. I'm experienced in soldering, and modding video game consoles so the wiikey was not much of a problem. I checked everything very closely with both my multimeter, and magnifying glass. Everything checks out okay. I used wires. You don't have to ask if everything is soldered correctly, or if there are any bridges. I checked VERY throughly with my multi-meter Over...and over again.. its all correct. I know your first reaction will be to tell me to check my soldering...but I know that is not the problem. I have re-done it about 5 times now, and still the same thing. The wii loads original games perfectly, as if no chip was installed. Backups however, will not load.....not even the setup disk, or gamecube backups...nothing thats not an original disk. This is really starting to bug me... I found i post about this same issue, but it really never resolved...The guy who started the post, just replaced his wiikey and then it worked.. Please, if anybody knows something that i'm overlooking.. or ANYTHING...please help. Thanks, L.
