PC Engine DUO-R Console Collection Item This item is being sold as junk with a defect, as the operation has not been confirmed due to the absence of cords and software. I have no knowledge of the PC Engine, so please understand that as well. Returns and exchanges are not possible. Please confirm everything before purchasing. I have lightly wiped the exterior, but the yellowing could not be removed. Serial number matches. To avoid any trouble, please refrain from purchasing if you are overly concerned about details. Thank you for viewing.
