Currently Wii games look like a blocky mess on my TV when playing them on the Wii U's vWii mode. This is because the vWii renders Wii games in 480p and the Wii U upscales that 480p picture to your TV's native resolution... it looks so bad that I've resorted to playing them solely on the gamepad screen.
However, I've heard that the Wii U is actually powerful enough to render Wii games in 1080p like Dolphin does, but Nintendo forcefully limited it to 480p so that it would more accurately represent a real Wii system... I really don't know much about the inner workings of the vWii system, but is it theoretically possible for a vWii homebrew mod to remove this limitation and allow Wii games to be rendered in a higher resolution?
