Ok so im a total newb in modding, im planning to mod my wii with a wiikey(first time ever handling a soldering iron) i did a serial number check and i gess i have the D2b chip set in my wii. If i was to buy a wiikey would it work correctly in my wii? Also i have been reading alot of horror stories about people and their firmware totally messing up with Super Mario Galaxy. Should i be concerned, i know AD has a huge amount of info but its very scattered. I was hoping that some professionals could help a curious newb in need?
