Hi Product Hunt! I'm Hans, and I built 1Retro because I kept losing game saves I cared about.

Retro saves live in fragile places: an SD card in a handheld, a RetroArch folder on a PC, a battery-backed chip inside a 30-year-old cartridge. Every one is a single point of failure, and none of them talk to each other. I was playing the same game on a MiSTer at my desk and a handheld on the couch, and my progress didn't follow me. It felt absurd that my Steam library gets this automatically while the games I've cared about for decades don't.

I assumed this was a file-sync problem. It isn't. Every emulator and device names and stores saves differently, so "just copy the folder" gives you conflicts and clobbered progress. The approach evolved into something deeper: per-device layouts (RetroArch, MiSTer, OnionOS handhelds, Steam Deck and more), full version history so a bad write can never destroy a good save, parsers that read the save and show what's actually inside, and a library you can export in full, so you're never locked to my service (an open save format spec is in the works).

The part I never planned: physical cartridges. Plug a Game Boy cart into a GB Operator and 1Retro backs up the save straight off the chip, next to everything else.

It's free to start. I'd love to hear two things: your worst lost-save story, and which device you'd want supported next.
