Hi, since I was on 3.2E and everyone has been saying to upgrade to system menu 4, I did this last night. Followed the ultimate guide and now I'm fully upgraded, however the sound on my wii is now terrible! Sounds like its too loud and very tinny like there is too much treble. There is no problem with the cables, i have both component and composite cables and both have this problem. I believe it to be caused by preloader as it was fine until i installed that! Anyone else had this problem? how do i get rid of preloader?
