This is a set of 3 Famicom (Family Computer) game cartridges. This is a popular set of 3 retro games: the enduring masterpieces **"Super Mario Bros." and "Super Mario Bros. 3," and Sunsoft's "Alien Syndrome."** [Important: Regarding the condition of the item] • Only the cartridges are included. (No box or instruction manual.) • There are signs of age, such as fading, scuffs, and damage to the labels. (Please check the photos for the condition.) • I currently do not have the environment to test the operation, so the items are untested (treated as junk). • We cannot guarantee operation after purchase. Please understand this in advance. • It may be possible to start the game by cleaning the terminals, but we ask that those who understand retro games and can perform maintenance or repairs themselves purchase this item.
