So from what I can gather, that adapter thing requires no soldering for the most Wii chips. You just plug it into the adapter and then plug the adapter into the motherboard, and you're good to go. If that's the case, then I think you two have helped me make my decision.
Thanks guys. This is much appreciated.
EDIT: Looks like the Wiikey requires soldering, but it's alright. I have someone handy who can solder.
EDIT II: I've heard rumors of systems being bricked when a game disk tries to update your system and it's been chipped. Is this true?
