This is a set of 5 Famicom cartridges. After purchasing these used, I cleaned the cartridges and performed contact cleaning. I have confirmed that they work on a compatible handheld Famicom system. * Mach Rider * Super Mario Bros. * Spartan X * Devil World * Galactic Battleship Gal Please check the condition in the photos. We are aiming for the lowest price, cheaper than anywhere else, so it's first-come, first-served. (We have set the lowest price at the time of listing, so please refrain from negotiating significant discounts for bulk purchases.) This is a well-balanced lineup, so please refrain from selling individual cartridges or swapping out the software. \* These are game cartridges from over 30 years ago. While they may not start up immediately on all Famicom consoles or compatible systems, they have been tested and confirmed to start and work on our shop's compatible system. We will ship via Nekopos in a water-resistant bubble mailer.
