You just have to pry open your Zelda cart to solder on a new battery for the static RAM :)
However I do think I’ve been exceptionally lucky not to have even one bad egg amongst my archive.
Ironically it’s not the games that’s caused me battery issues but the consoles themselves. My Saturn, Dreamcast and Xbox all needed to have batteries replaced despite being several generations more recent.

The late 90s/early 2000s had a very unique and IMO under appreciated aesthetic.
