First off, please don't say to use the search box or look at the other threads, because I have and havent found out answers to my questions. 1. I have heard people talking about things like chipsets, and I am wondering if some chipsets arent compatible, and how I would find out if my wii would be compatible. 2. does it run off of CDs or DVDs? I don't have a DVD burner, so I really need this answered. the files are iso which, in the past, I've always used for CDs, but i dont know what file type a dvd image is, so would CDs work? 3. is wiikey the best or only the most popular? does it have more features, more support? I would like a cheap chip but not if it does less than one that costs $10 more. 4. Does it really matter what soldering iron I use? I have one but i dont really know anything about it, i dont know if its 15W. please, if you know the answer to my questions please answer them instead of telling me to search. I tried searching, and if you're gonna post, atleast help me out.
