I bought them all separately on Ebay from different sellers so they're probably not from the same owner. 99% of my NES cartridges still can save so it seems extremely odd that 90%+ of the Genesis carts wouldn't save, unless Genesis carts are notorious for not saving. It seems as though the console is wiping out the saves. Or I could just be very lucky with NES carts and very unlucky with Genesis carts.
