A not-so-fun fact is that this even applies to modern read-only media, most notably Nintendo game carts. Back in the day they used mask ROMs which ought to last more or less forever, but with the DS they started using cheaper NOR or NAND flash for larger games, and then for all games with the 3DS onwards. Those carts will bit-rot eventually if left unpowered for a long time.

I've noticed a number of GBA carts I've picked up used (and probably not played in a long while) fail to load on the first read. Sometimes no logo, sometimes corrupted logo. Turning it off and on a couple of times solved the issue, and once it boots OK it'll boot OK pretty much every time after. Probably until it sits on the shelf for a long while.

Do we have confirmation that the carts are able to refresh the data?
