Thank you for viewing. This is Super Mario Bros. DX for the Game Boy. It's the North American version, but it works on Japanese consoles. I have confirmed that it works on my Game Boy Color. The console used for the operation check is not included. This is a valuable game that was only available through rewrites back then. No box or manual. Cartridge only. I think it's in relatively good condition for its age. #GameBoy #SuperMario #Nintendo #Game
