This is a Dreamcast Visual Memory. Since I don't have the Dreamcast console, I haven't confirmed the save function. I have confirmed that the Visual Memory itself works. I was able to operate it without any problems, so I don't think there are any issues with the buttons. There isn't much discoloration, but there are some minor scratches. For safety, the batteries will be removed before shipping. Please purchase two CR2032 batteries at a 100-yen shop or similar store.
