Homebrew makes wii 4:3

[Cacapiko]

I use a Wii U for playing hacked brawl, and i recently got an update that makes me able to play games on the gamepad. Homebrew works fine as always, but ever since that update, homebrew makes it so every time i launch it, it makes the screen 4:3 (Square with black bars on the sides), including when i launch Gecko to play brawl. The wii menu beforehand is perfectly fine and widescreen, anyone know how to fix this?

I know nothing about Wii mode on the Wii U, but...
Is it set to widescreen in Wii mode?

That fixed it for me.
