I currently have a release date wii with a wiikey installed. I was wondering if this is the only chip out of [wiikey / D2Ckey / D2PRO] that I can have installed? It is self-installed, and there's no problem to take it out and install the other chip if necessary. If I want to upgrade chip, do I need a newer D2C wii? If that is the case I can swap Wii's with my friend because she wants one modded and has a D2C unmodded Wii.
