Sega Mega-CD Backup RAM Cartridge I don't have the console, so I haven't confirmed its operation. I don't know if there's anything recorded on it or if it's unused. The instruction manual and label also look like they haven't been used much, but they show signs of aging. I am selling these items, which I received from a relative. They are all over 30 years old, so while they are in good condition, I cannot guarantee the product's functionality. ⚠ Please be aware that returns are not accepted to prevent swapping. If you have any questions or would like additional photos, please ask in the comments section.
