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 a Game Boy Advance port of Super Mario Bros. Like Mario's mushroom, the color of the cartridge is cool red and white. Super Mario Bros. A well-known masterpiece. The origin of Mario. It's moving to see what Bowser looked like in the beginning. How about commemorating Mario's 40th anniversary? This item has been stored by a private individual. Please refrain from purchasing if you are concerned about minor details.
