This is a Visual Memory for the Dreamcast. I have confirmed that it powers on with batteries inserted, but I cannot confirm further details as I do not have the controller. Therefore, I am selling it as junk. To prevent battery leakage, the batteries will be removed before shipping and are not included. Please prepare batteries yourself. Returns and exchanges are not accepted after purchase. No price reduction. Please purchase if you understand that this is a used item. Please refrain from purchasing if you are sensitive to items stored at home. Thank you.
