Emulator Problem: Blowing on the screen?

Hi, there! I've done my best to search for this topic so as to not create a repeat thread, but I've found nothing on the subject, so here it is. I apologize in case, for all my searching, the question has already been asked. My question is this. I'm playing Phoenix Wright Ace Attorney, and have become stuck at a point where the character needs to blow on the screen. This can't happen for obvious reasons, so I was wondering if there was at all a way to bypass this? I'm checking all of the options, but nothing's jumping up at me, nor has every manner of hyperactive mouse waving done anything to help things. Any and all help would be much appreciated! Thanks in advance!

Nevermind! I've since searched some more, and found the answer. No$gba is really quite something to enable blowing through the mic. Very clever.

Shouldnt have been a problem to begin with, since you actually dont blow on the screen on the DS, you have to blow in the mic...
