I've read the topic about which modchip does what, and i am almost certain I have a wiikey, but i need confirmation. I bought this wii from china, so its a ntsc-j wii, it was pre-modded, and i do not know what modchip it is. I don't want to open up my wii fearing mistakes that I will make and the absence of tools that I have in order to open it. there are probably threads about this already, but search is disabled =( I remember asking the person who sold it to me if i can play NTSC-U games and she said that it can. She also said that it is able to play any ntsc game. Is mine a wiikey? How do I check without opening it?
