So, I just downloaded the No$GBA DS emulator and all that, and now I've got a problem. Whenever I try to play Heroes of Mana, or any other rom for that matter, it starts working fine. But as soon as I try to interact with it in any way, the screen goes black and stops working. So, is there anything I'm supposed to do before trying to play a game? Or is there any other problem this could be? Any help would be greatly appreciated.
