At its peak, Game cartridges used RAM and a backup battery to save game advances and player profiles. Over time those batteries tend to run out and leak hazardous materials that may cause personal injuries, data loss and permanent damage to the cartridge.
With this upgrade you can solve all those problems by replacing the original RAM chip for a Non Volatile Memory (NVRAM) that does not require a battery to save your data, it means no more batteries, no more cartridges damaged by battery leaking, no more game records lost!
