also, do NOT use AnyTitleDeleter despite it saying it that it removes more traces of a title than what data management does (which it does) it ALSO uses a fake IOS0 ticket to get access to stuff ... and it leaves it behind when it's done which Ninty has been known to spot on repair jobs.
Luckily, vWii doesn't have as many modifications that can be done to it to it as a Wii so there's nothing like PriiLoader that's gonna leave behind evidence but it's still tricky ... even if it's not impossible. (and if you've used the IOS80 patched you're kinda screwed unless you can find a good source for a CLEAN IOS80 vWii WAD to replace it with and if you remove it you're BRICKED.
