The amazing USB-C gadgets that play old Nintendo cartridges

Last week, I powered on a 26-year-old copy of Pokémon Pinball, one of the best Game Boy games ever made. My save file was no more. The Charmander I'd caught for my daughter, the high scores we'd set together… gone.

Before flash memory, Nintendo cartridges used tiny watch batteries to save their games, and those batteries were never meant to last this long. But it's not a huge deal, because I saved my family's save file months ago.
