No$gba help needed

Hi, I'm new to this whole emulator shabang and I'm obviously doing something wrong because this No$gba emulator isn't working with the NDS games I've downloaded (only two so far from this website - Pokemon Pearl and Ninja Gaiden).Anyways, I've downloaded No$gba only, do I need to download/configure anything else so NDS games would work?The GBA games I've downloaded are playable without any configurations or any screw-around work with it so...I don't know why the NDS games aren't working. I'm really confuzzled, please help. ???Thank yous.

my advice is to try dualis, it worked fine for me

Or use iDeaS, I just tried to play Ninja Gaiden yesterday on no$gba but the backgrounds don't show no matter what setting.
