Thank you very much for viewing our page. This product is only the game cartridge, as the box and instruction manual are missing. Please check the images for details on the condition. To ensure the game's save function works correctly, a socket-type battery holder has been soldered on, and a new Japanese-made button battery has been installed. Operation has been confirmed on a genuine game console, and the inside of the cartridge has been cleaned. We will ship via Nekopos, with measures taken to prevent damage and water damage. We are unable to negotiate the price due to the cost and effort of replacing the battery. Please consider the listed price. Returns and exchanges are not accepted to prevent swapping, etc. Also, please understand that this is an old item, and there may be scratches and stains due to age.
