Do things like the upgradable firmware and integrated text editor live in a path that's separate from the 8KB of data? If not I'd fear it would die before the actual storage did.

I also vaguely recall that Sonic 3 used this storage type? Like it was a weird outlier for cartridge-based saves IIRC.

Edit: Yeah, it did: https://hackaday.io/project/13425-sonic-3-feram-adapter
