Hacking So I'm about to buy a WiiKey...

Shoot.
Reading again into some things, apparently GC2-D2B doesn't work with the Wiinja. Does this mean the same for the WiiKey? I have no way of checking right now I sure hope this isn't a problem if I have it.

The first Wiinja, wiinja v1 didn't support D2B chips, but that was a long time ago. Wiinja v2 and Wiinja Deluxe supports D2B chips. In fact all currently available modchips support D2B.
