Well, you would need access to our usb exploit. Basically, it works like a "badusb" but instead of tricking something to think its a keyboard the device still sees it as a usb mass storage. But it has no clue that the usb stick itself is hiding a payload that injects at "checking drive please wait".
This exploit we call the Grace bug (like a gift from the heavens) can be used to attack pretty much every software on the market.
As nothing yet has been released to thwart it. (because it's not out to public yet) We feel that the wii u making it to firmware 6.0 would be the best suited time to release it. (along with all source code so it can be used in other operating systems) It will take different hardware to make any attempt at patching what we plan on releasing and it may come with some blowback. (not really worried about it but most of us do not want to make the news) I was more attempting to tell you if you were so inclined to do so, you could build your own exploit on that console if it is still on 1.x firmware rather easily. But, since you are looking for downloads of an already polished exploit, I am gonna guess you would be better suited with finding a 5.3.2 game and update to that. (Just my two cents) Only members of my team have access to the "grace bug" and we require some fairly heavy usb programming experience to become part of us. So, just get yourself up to 5.3.2 and forget us til 6.0.

This is what everyone should build to troll the wii u hacking scene as webkit homebrew..............lol (Sorry had to join in on the overuse of punctuation.)
