This is a listing for a junk item, a WonderSwan Color by BANDAI. I inserted batteries, but the screen only flashed momentarily, and no games could be played. The main unit does not turn on, so I haven't been able to check if it boots up, but one game cartridge is included. Please only proceed with the purchase if you understand that this is a junk item. - Brand: BANDAI - Model: WonderSwan Color - Accessories: Game cartridge (Digimon) - Country of Manufacture: Japan Thank you for viewing.
