My Wii is on System Menu 4.0U. I bought it a year and half ago, so was able to softmod it with BannerBomb, install HBC, Wanikoko's cios 38 as 249 and Herme's cios 37 as 223. I also have BootMii as boot2. I love this setup. What do I do if I run a game off disc and it wants to do a System Update? This actually happened with Guitar Hero: Smash Hits. Do I install it and pray? (I did with GH:SH, and other than updating some IOS's, it didn't mess anything else up, thank goodness). Can Nintendo mess with BootMii or ios 223/249? I know I can run games off HD only which I think skips update checks, but there are some I can't, like Rock Band because DLC doesn't work, and the timing gets messed up sometimes because of hard drive lag.
