This is a wireless controller made by NEC for the PC Engine. The exterior is in relatively good condition, but there is rust inside the battery box and some of the metal fittings are detached. Since I don't have a PC Engine console, the operation has not been confirmed. - Model: PiPD12 - Type: Wireless Controller - Brand: NEC - Color: Black/Purple - Number of buttons: 6 buttons Thank you for viewing.
