I have a problem with two nds emulators

[Stephen McGiourson]

I am trying to play nds roms with the NO$GBA emulator and when i'm choosing a rom to play it starts normally but after a while a message appears saying "Could not read the data. Turn off the power and reinsert the game card", and that happens in any game im trying to play.I also tried another emulator for NDS, the IDEAS emulator but i cant open that one...can anyone help me with this?
