only 2 things u can do to a Virgin wii and have it keep its virginity
1) as mentioned earlier, using pussyloader to copy restricted gamesaves
2) if you bannerbomb (or any exploit) any kind of app that doesn't have any cIOS dependencies (ie. some older emulators... before they started using cIOS202), it would also retain its virginity
okay, and there is also a 3rd way, u can connect an infectus mod chip to your nand, and copy it, without affecting its softmod virginity.
edit:
everything else requires one or more of the following: cIOS, HBC, BootMii, or DVDx
edit2:
don't u just hate virgins? They only play with their pussyloaders and miss out on the good stuff
