As above, i've noticed I got many strange entries in my UID.SYS probably due to forwarders and whatnot. Is it safe to hexedit to remove the entries? Is there a "virgin" uid.sys I could just overwrite it with? will it brick? Also, in the WiiFS wat exactly does AnyTitleDeleter do? It deletes the tickets and titles? What other things are left behind that ATD can't delete (eg UID.SYS entries). Also, is it safe to delete ALL NUMBERED IOS except IOS60 just for system menu 4.0? (I don't want to see any "don't deletez any IOS or you will brickz" post please) Of course I'll leave a trucha patched IOS around. I have many folders in shared2 as well. Other than SYS folder, are the rest important? Menu, wc24, test1, test2, successi, ec??? Btw I don't have a vulnerable boot1, if not i'd be more than happy to try deleting them out by myself. Also, i've tried to research on "virginizing" the wii, mainly because I've been fooling around with all sorts of channels/hacks/wads/ios/blah. Now that I know the cleanest and best way to get such things done, I would like to "clean up" the wii. I am aware that there are no "benefits", but I still want it to be clean. OCD, as some of you put it here. And also has anyone tried Comex Formatter aka BrickMii?
