A set of 22 Famicom cartridges (some duplicates) & a bonus (a bootleg Famicom). I've confirmed that they all work, but the bootleg Famicom's performance varies. Please consider purchasing only if you understand this. *Please consider purchasing only if you understand and accept the condition, as they have been stored at home for a long time. Also, please refrain from purchasing if you are overly concerned about the condition. Due to the nature of the product, such as to prevent swapping, returns are not accepted. *I have many other items for sale, so I would be happy if you would take a look.
