DS Trouble

yeah hi...I've been playing the Digimon World for the DS using the no$gba emulator and it was working great and everything
but when I got on it today it was lagging in a way, the audio starts to mess up and well eveything starts to mess up?
any suggestions on how to fix it?

It was working fine before? Try to exit a few processes.

I got it fixeddo you know any good reason why everytime I play Poke'mon Diamond it pops up saying "microphone failure"?

Do you have 2.6a? Also, what kind of sound card do you have? Many things cause the Microphone Wave error.

yeah I have 2.6a, and I don't really know what sound card is in this comp but I'm guessing it's a weak one lol
