Thank you for viewing. Regarding operation verification: I checked the item with my own console just before listing, but I cannot guarantee that everything will work. For cartridges with a backup function, I have not checked the battery level. Please refer to the photos for the condition and understand that this is a used item. [Other] There are no pets in the storage location. There are no smokers in the family. Returns, refunds, and exchanges are not accepted. Thank you for your understanding.
