Emulator Problem: Weird Dolphin graphic bug in Legend of Zelda: TP

Hey guys, i'm a total emulator newb, i downloaded Legend of Zelda for wii, launched it with Dolphin from the ISO. There weren't any warning or bug messages, everything went until i got to the actual game. This appears when i try to play it (cutscenes and menus are ok)

What do? D:

As far as I know there isn't much you can do about it, you can always try fiddling around with plugins and settings though.
