Hello all you Dreamcast Fans what I have up for auction is an official microphone adapter (HKT-7200).  The microphone adapter has been tested and is in good working order.  This microphone adapter is used for cool games like Seaman and Alien Front and ships Fast & Free.  An OEM mic is not necessary to use this adapter. Any wired mic with a 3.5mm jack will work!  Any questions please just ask and bid with confidence as my feedback is excellent.
