EmuSync vs Game Save Genie

EmuSync syncs game saves between devices by linking save locations to shared storage. It is aimed at people who play emulator or non-Steam games on multiple devices, and at anyone seeking another save backup. Storage can be a local or shared folder, Google Drive, Dropbox, or OneDrive. Users can configure save locations, let the app detect saves, and choose automatic or manual syncing. EmuSync also provides local backup and manual restore. Steam Deck users can check sync status with a Decky plugin without switching to desktop mode. Advanced users and scripts can use its local HTTP API, which requires no authentication and is documented as available only on the device, not over the network. The privacy policy says personal information is not collected, stored, or transmitted; app data stays locally or with the chosen cloud provider. Windows 10 and 11 x64 are confirmed working, and Linux instructions cover Steam Deck. The project says it cannot currently build and test for Mac and has no plans for Android or iOS. Its Windows installer is unsigned and may trigger a SmartScreen warning.

Game Save Genie backs up and syncs PC game saves for games without save protection from their launchers. It uses the Ludusavi database to locate saves for more than 19,000 games, and users can track folders and files manually, including emulator saves. Backups run when a game closes and every 10 minutes while it runs. Each backup is an immutable, checksummed snapshot, and users can restore a selected version. The tool supports Google Drive, OneDrive, S3 buckets, and other rclone destinations; unchanged save files are not uploaded again. Users can pull newer saves onto another PC, with save paths remapped across Windows, Linux, and macOS usernames. Before restoring, it verifies and stages downloads, makes a safety snapshot, and avoids restoring while a game is running. The project says it has no accounts, servers of its own, or telemetry. Windows single-machine backups are described as stable; cross-machine sync and Linux/Steam Deck support are beta. It is free and MIT-licensed.
