Does the Dreamcast microphone test work for everyone else? After I record and hit playback, I can only hear static. I tried both 11khz and 8khz, with the pad on and off. Just static. I did buy it used, so I'm wondering if the microphone no longer works.
It was developed and tested using three microphones, but your model might differ. Could you check the device information under the hardware tools -> Maple Device List? The select the microphone and press A. A screenshot of the resulting data will tell me if this is a different model that has different characteristics.
