Thank you for your interest in the Famicom Disk System set. [Condition of Item] Belt replaced. Head adjusted. Functionality tested with 5 different games, and they all worked without issue. The original Mobilon band slips, so it is not used. A compatible band is used instead. Regarding the details, "It is slightly wider and thicker than the original Nintendo band. It has a solid shape, is easy to handle, and feels durable and reliable due to its thickness. Although I haven't measured it, I believe it will last longer than the original Nintendo band." [Included Items] This listing includes the Famicom Disk System unit, RAM Adapter, AC Adapter, and box. The TV, games, and Famicom console are all sold separately. xa5 FAMICOM DISK SYSTEM FDS RAM ADAPTER AC Adapter HVC-025 HVC-022 HVC-023
