My second theme, Legend of Zelda Themed....yeah(disclaimer: Rhyguy is not responsible for the damage it will cause to your life due to its uber pwnageness...ness)
I don't have a wii u anymore to test it myself, but if homebrews are not visible on the wii u menu I think you can press L + R + minus to open the plugin menu, there should be an option called "homebrews on wii u menu" or something similar
