Problem with Rondo Sword

I have download rondo sword rom, but there is a problem. when i load the rom, the screen become black.
i used No$GBA as emulator.thank's.

change your nds backup media on the options menu

I have changed the media backup, but it still same.

Rondo of Swords doesn't currently work in any of the emulators out right now. You'll have to wait until a new update and hope that it fixes the problem.
