i have searched the forum and can't find an answer to this particular question. i am currently using version 3.2U. i don't use the Twilight Hack because i already have the HomeBrew Channel installed. however, i have used WUM to change the updates on discs so that my Wii doesn't ask to update to 3.3U when i play newer games. is using WUM to change updates considered signing? if i do update will these discs stop working? with my current setup, what other problems would i run into if i updated?
