Knights in Nightmare (U)

I have been having this problem with the ROM.
The top screen flashes and isn't very clear as far as I know the game still works it just flashes and the top screen's barely visble
I checked the Japanese version as well is this just a problem with the download itself or am I missing something?
I'm using No$gba 2.6 emulator
