4MB expansion RAM cartridge for the Sega Saturn, an essential item for improving game performance. Thank you for viewing. I am selling off my collection as I am preparing for the end of life. I will be listing games, anime goods, and more. These are items from my collection since the Showa era, and as a collector, I have stored them with care. The condition will be described for each item. I will cover the basic shipping costs. I will wrap the items in bubble wrap before shipping. Please feel free to ask any questions.
