Dungeon Explorer DS

Hi guy's. i got stuck in pyramid and there is some a glitch, the screen become dark. ???Edit : after preventing Evil Egg born to the world. thank you. i am using NO$GBA 2.6a as Emulator

Go to the pyramid again and see if it happens again. If it doesn't, it was just a one time thing. If it did it again, try changing some of your setttings.
