Thank you for viewing. This is a Game Boy game, Momotaro Dentetsu and Doraemon. I bought them new back then and played them as a child, then stored them for over 20 years. I wrote my initials on the back with a permanent marker at the time. The horizontal lines at the bottom of the screen are due to my Game Boy itself. I have confirmed that they start up. Since they are old, I cannot offer any guarantees. Please check the photos and understand that they are used and vintage items before purchasing.
