Crayon Shin-chan 4 game software, with instruction manual and case. I do not own a Game Boy, so I have not confirmed that it works. However, if it doesn't play, I will accept returns and refunds, with me covering the shipping costs. When you insert the software, it's very old, so the connection may be poor at first. Try inserting and removing it a few times, and blowing on it (like you would with a cartridge) – this often fixes the problem. If that doesn't work, I will provide support. The instruction manual and box have damage, scratches, and warping. The top lid of the box doesn't close properly. Please be sure to check the photos to make your judgment. I will sell it to those who are okay with this. - Game Title: Crayon Shin-chan 4 - Brand: Bandai - Model Number: DMG-H9J - Included Items: Instruction manual, case, outer box - Country of Manufacture: Japan Thank you for looking.
