NOTE about the new wii and the wiikey fusion
Link about the new slimmer wii: New Wii console coming before Christmas - Official Nintendo Magazine
Since EU is getting this first, SOME of you will need to know the differences between the old and new wiis and the wiikey fusion may not work without a drastic interface update on the new wii.
Things about the new wii:
GC functionality is gone.
Things about the wiikey fusion:
It uses a GC interface for selecting a game and update.
It will likely not allow you to boot into the wiikey fusion menu since it uses a GC interface. Weither or not the new wii will have GC disc option removed to only show a wii disc only under the disc channel.
The no GC on the new wii will apply to all disc emulator hard mods that use a GC interface, another such one is the sundisk.
