This is a Game Boy Color cartridge of Pokémon Crystal Version. I've confirmed it works up to the early stages of the game, but I haven't checked the entire game. Would be suitable as a repair base. The save backup battery seems to be dead. This is a junk item, sold as-is, assuming it needs repair. Please only purchase if you fully understand the meaning of "junk." The listing includes the cartridge only. Other accessories are not included. There are scratches, dirt, dust, sticker degradation, and rust on the screws. There may be scratches that are not visible in the photos. I haven't captured every detail in the photos. The actual item may have more scratches and dirt than shown in the photos. I will wrap it in bubble wrap, put it in an envelope, and ship it via Nekopos (domestic Japanese shipping service). Please understand that this is a junk item, sold as-is. I purchased this item used myself, so there may be oversights. Please only purchase if you understand the contents of the description. #GameBoyColor #GAME BOY COLOR #GAME BOY #GameBoy #Pokemon
