Yeah, but they are called prod.keys. Yuzu has a getting started page. It will tell you how to get your own prod keys from your switch, but you could see if condone put them up online. But I wouldn’t know anything about that 🏴‍☠️

I haven’t tried with Switch saves, but I sync saves for several other platforms using Syncthing and it works perfectly. It’s a set-it-and-forget-it solution. You just have to find the folder where the saves are stored and set up a sync. Whenever your devices are on the same LAN, they’ll sync the saves and you’ll always have the latest one on all of them.
