I have confirmed that the game loads on my Game Boy Color. The box and instruction manual are not included. A sticker of "Wanpaku Kozo" is on the back of the cartridge. * Regarding software with built-in backup batteries, I do not guarantee the battery's functionality. * I only guarantee initial functionality. Returns for reasons beyond initial startup confirmation, such as "stops during gameplay," will generally not be accepted. This is a used item and has been stored at home. Please purchase only if you understand this. To prevent swapping, returns and exchanges are not accepted after purchase. The item will be shipped in an OPP bag and bubble wrap.
