Alright so after downloading quite a few wads from newsgroups, i stupidly installed them before checking what region they're from. With most being PAL my NTSC wii couldnt do a thing lol. So i decided to delete them using the wii channel manager. Then i went looking online and found out theres a .wad uninstaller application out there. 1) Whats the big difference about deleting the channel using my Wii vs using the wad uninstaller? 2) Does this mean that for my wii, nintendo will see traces of my illegit wad installs? 3) Will formating my wii internal memory make all of these traces disappear? I just got my wii, so i can live with killing all my save files.
