Maybe try redownloading the ROM... If that's not the problem, try to see if other games have black screens at the top as well.

What flashcart are you using?

Was there A/P in this game? That might be the cause. Patch it. But this has been said MANY times before. Google is your friend.
OR you update latest firmware etc...
