So the keys the Wii used is baked into the source code for Dolphin, which is a major no-no and why Nintendo decided to finally go after them and their Steam release. Modern Vintage Gamer did a video on this yesterday, and actually showed the source code (blurred out so he wouldn't get DMCA'ed also) literally showing the keys in the source code. Not sure why the Dolphin team did that since again it's considered a major no-no for emulation teams. But, hopefully they can fix the situation easily and fairly quickly. The Gamecube keys aren't included, just the Wii. So it seems removing the Wii keys from the code would be the easiest solution, but I am not a coder so I don't know how difficult it would be.
