I have confirmed that the game can be read on my Game Boy Color. There is a price sticker on the outer box, and there are scratches on the box due to aging. Please check the photos. All accessories are shown in the photos. * We do not guarantee the battery for software with a built-in backup battery. * We only guarantee initial operation. We generally do not accept returns for reasons other than initial startup confirmation, such as "stopping during gameplay." These are used items and have been stored at home. Please purchase only if you understand. To prevent replacement, we do not accept returns or exchanges after purchase. We will ship in an OPP bag and bubble wrap.
