The X BAND Super Famicom communication modem main unit is a retro game accessory that allows gamers to connect and play their favorite Famicon games with others. Made by the Famicon brand in Japan, this unit is perfect for fans of classic gaming looking to experience nostalgic gameplay with a modern twist. This modem has not been tested nor I have expertise on it. Overall in great condition in my opinion but please look at pictures. As is not tested.
