no im sorry my board is rev A/B, but that is really weird maybe something is jumped between your 12v line and your 3.3v line so the 12v is coming out. just a guess.
Just want to thank everyone here for spending the time to create tutorials. Thanks to this community the wiikey was successfully installed on my first try, but unfortunately my gc has the old bios so I have to hold down one of the buttons while i boot the system up, and even then it only works...
Im looking for a device that allows me to easily plug in my wiikey fusion to my game cube without the advanced soldering. If nobody has one, I could always use some tricks to making this as easy as possible.
