None of this will work. Simple fact is that the wiikey is at the end of its life as a product. The majority of people buying chips now need D2C chips. Normally good business practice is to support end of life products in order to develop a good reputation and consumer loyalty.

It's almost certainly just a matter of time, but until an exploit is found no one will have any idea how long it will take. Try to get your hands on a D2B (even if the legs are clipped it can still be modded).
