Using Mic on Desmume

Help please!

What specifically are you having trouble with?

His/her topic says that.. he/she want to know if he/she can use mic on Desmume................as far as I know.... Desmume didn't have an option to use Mic. ;D
I think...

Try to plug in some thing with a Microphone, i think that if you blow, you use the mic...
