Thank you for viewing. I have confirmed that it works. There is no outer box or instruction manual. Everything in the photos is included. This is the Game Boy Advance port of Super Mario Bros. 3. It features Tanooki Mario and the enemy character Boom Boom. There is also a Mario Bros. mode, so you can enjoy two different games. If you are concerned about the save data, please erase it and enjoy. We are not responsible if the game is in its initial state due to the delivery process.
