Please read the profile before purchasing. Game Boy GB Contra: The Hard Corps & Bird Spirits I have confirmed that it starts up on the Game Boy Color and have only checked the opening sequence. I do not guarantee that it will start up on all models (including compatible consoles), nor do I guarantee its functionality. Please check the condition in the images. I haven't shown the ear part on one of them because it's firmly attached and difficult to open without force. The software has some damage, but the other accessories seem to be in better condition. Please note that the battery and save functions are unknown. Please refrain from purchasing if you are overly concerned about the condition. Returns and refunds are not accepted. If you have any concerns, please do not purchase from me and instead buy from another seller or a store.
