Well im still yet new to all this but I can do alittle, I have a couple games on my external hard drive formated as WBFS and I use WBFS for MAC OSX to put games onto eh the hard drive and use uLoader to play them on my wii! And I have just put COD black ops on it. I have been reading that you cant play on on cios 224 ? But what im wondering since im still all new to this if I wanted to play black ops what would I have to do and if I was to I think I read was to use cios 224-57 ? If I was to do that could I still play all my other games on my HDD and if I was to do something wrong would I / or could I possibly do anything to harm my wii !?
