Hey, I've got the ideas NDS programme for playing. Whenever I open a NDS game rom to play, it lags, freezes, the sound goes funny and it goes slow.
Does anyone know the problem or how to fix this?

Plus, I've got the No$GBA NDS programme too, but when I open a NDS game file, it says "Cartridge not found"

Please, help, thanks.

Goto Optimal Settings:

Look at the part about NDS Cartridge Backup Media. That's the one you want to change. You'll need to change that to the correct format for your ROM. (Or if you have an option called Auto, select that.)

I cannot get to the Optimal Settings part. It tells me to choose a rom, and theres no options, then it says cannot find cartridge.

Theres no tabs on my Emulator, its just black telling me to choose a rom, no option settings.

You don't see the options menu at the top of this image?
