I know these have been done, but I want to do a Let's Play on a game which I have on Snes9x, but whenever I record on it, I can't get my own voice to record with it, even though I am using a microphone which I know works perfectly.

I have tried both "movie record" and "record avi" for this, and also note that as of today, "record avi" keeps crashing the program, but that maybe because I messed about with the settings.

Is there away to record my voice while recording my playthrough?

Note: it's an edit of FF6 staring characters from a TV show, and I own FF6 in real life. (I'm afraid it's ponies again, and yes it is out of date now, but I still want to do it.)
