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. The game has been tested and the inside of the cartridge has been cleaned. We will take measures to prevent damage and water damage, and ship via Nekopos (a Japanese delivery service). We are unable to negotiate the price due to the cost and effort of replacing the battery. Please consider the price as listed. Returns and exchanges are not accepted to prevent swapping, etc. Also, please be aware that this is an old item, so please forgive any scratches or stains due to age.
