Highscore saving is different from standard cartridges: While normal carts use battery-backed up RAM, this one uses a 512k SPI flash to store high score entries non-volatile. This makes the cart a lot more compatible with today's environmental requirements, as it can be built without battery and without electrolytic capacitors, putting it into the lowest-impact category from an environmental perspective.
