SaveSync vs RomM

RetroArch save sync, without running a server.

RomM is an excellent self-hosted ROM library, and since 5.4 it can be a server for RetroArch's Cloud Sync. If you only want your saves to follow you, SaveSync does the same job with nothing to run.

Start syncing

Choose SaveSync if

  • You want save sync without running Docker, a domain, and HTTPS at home
  • You want it to work away from home without opening a port or a VPN
  • You don't want to look after a server's updates and backups

Choose RomM if

  • You want a ROM library with metadata, box art, and downloads to your handhelds
  • You already run a home server and like keeping everything on it
  • You want Argosy or Grout to sync standalone emulators on your handhelds today

What running RomM takes

RomM runs in Docker with a database. For a handheld to sync away from home, the server needs a public address with HTTPS, or a VPN like Tailscale on every device. When the server is off or its certificate expires, syncing stops; when its disk fails, so do your saves, unless you back it up.

Switching from RomM

In RetroArch's Cloud Sync settings, change the URL from your RomM server to SaveSync's, with a SaveSync key as the password, on the device with your newest saves first. RetroArch uploads its saves on the next start. Then change your other devices.

Setting up takes a few minutes per device: see the Cloud Sync guide, or the one for your device.

Questions

Can I keep RomM for my ROMs and use SaveSync for saves?
Yes. They don't overlap: RomM manages and sends your ROMs, and RetroArch's Cloud Sync sends saves to SaveSync. Just don't point Cloud Sync at both.
Does SaveSync store my ROMs?
No. SaveSync stores saves and save states only, never ROMs, BIOS files, or games.
