I updated my Wii using ModMii and I also installed which installed cIOS249rev20. I thought I saw somewhere that I needed a cIOS246 with a base of 57 in order for COD:BO to work. So I downloaded cIOS249rev19 and installed it. COD:BO keeps doing the same thing....it just hangs up on the Loading screen. I have not been able to get to the Main Menu yet. Am I doing something wrong, or do I need to do something else? Does the USB loader I use matter?
