Mario Kart Wii - Top Left Rectangle

[FrangoST]

Finally managed to activate the gecko code to make the game run full speed at 30 fps and noticed that the trophy scene doesn't have the rectangle at the corner... maybe this could be helpful?

Edit: Other specific circuits don't have the rectangle, too.. Like Coconut Mall and DK Summit....
Edit2: Grumble Volcano is bug-free, too...
