I know that microphone support has been implemented in v2.3d or somewhere close, but I tried blowing at it during WarioWare Touched! and nothing happens. I have a good microphone and tried every setting possible (sound input/output, microphone boost, etc) and nothing.
I'm stuck on that game where I (as a robot) have to blow a dust on the window and there's no way I work around this without microphone support.
Any ideas? I'm currently using v2.6 (free), by the way.
