This is Contra (known in Japan as Gryzor) by Konami for the Famicom, a Japan-region cartridge.
The set includes the cartridge, box, and manual, and has been tested and confirmed working. The box shows edge and corner wear, some color fading, and creases at the opening flap, and the cartridge's rear warning label has a small tear with a missing piece on the left side. Please see the photos for the actual condition.
