I am selling a set of three Family Computer (Famicom) cartridges. This is a popular set of three retro games, including the long-loved classics **"Super Mario Bros." and "Super Mario Bros. 3," as well as Sunsoft's "Alien Syndrome."** 【Important: Regarding the condition of the items】 • Cartridge only. (No box or instruction manual) • There is some discoloration, scratches, and label damage due to aging. (※Please check the condition in the photos.) • Currently, there is no environment to test the operation, so the operation is unconfirmed (treated as junk). • We cannot guarantee the operation after purchase. Please be aware of this. • There is a possibility that it will start by cleaning the terminals, but we ask that those who understand retro games and are able to maintain or repair them purchase this item. 【Product Contents】 1. Super Mario Bros. (HVC-SM) 2. Super Mario Bros. 3 (HVC-UM) 3. Alien Syndrome (Sunsoft)
