I have confirmed the operation of the Sega Saturn 4MB expansion RAM cartridge included with X-MEN vs. Street Fighter. This is a retro item, but it is in relatively good condition. Operation has been confirmed on a Sega Saturn console. As this is a retro item, there may be scratches, stains, scuffs, and wrinkles. This item is not suitable for customers looking for a product in new condition. Please understand this before purchasing. Thank you for viewing.
