I get the wii system files are corrupt message after exiting some games. To get the message to go away I need to load the homebrew channel from preloader and then the message goes away and wii menu boots fine. Any idea of why it only happens after certain games and if there is anything I can do about it? My wii is 4.1u and I am using preloader .29 modified to support new homebrew channel. I use a usb loader to run my games. At this point I would prefer not to update preloader or go to 4.2 but I guess I will if I have to. Thanks for your help.
