Clear Purple Communication Cable Thank you for viewing. One end is a cable compatible with Game Boy and Game Boy Color, and the other end is a cable compatible with Game Boy Color. I believe it was for communication. I apologize if I'm mistaken (>_<) It's quite old, and I can't confirm its operation because I don't have two consoles. Please purchase it as a junk item. Returns due to product defects are not accepted. ★Please check my profile before purchasing. ◆◇◆◇ #GameBoy #GameBoyColor #CommunicationCable #Purple #Game #Nintendo
