How please?

You need a modded Wii U, and Homebrew Appstore. Wii U Shell. it can view images. you also need the screenshot unlock plugin for aroma cfw. aroma is basically limitless, as long as the gates are open, not even gandalf can stop home-brewed spell casting.

i hope that helped, i shall cast myself outta here with my awful lord of the ring references-turned-dad-joke.
