Browser Game Saves: Back Up Progress Before Switching Devices
Tell game saves, emulator states, imported data and saved guide links apart, then check what your selected game can export.
Know what you are saving
A game save records progress. An emulator save state records a particular runtime state and may require the same emulator build. Imported game data supplies resources and is not a progress backup. Saving a game in Radiant Games bookmarks its guide; it does not copy an external game’s progress.
Check the original game’s save menu and the host player’s controls separately. Warcraft II’s in-game saves and its host’s emulator options are different layers. Do not assume a host has cloud sync because it offers an account.
Export before clearing data or changing builds
The Mindustry web port documents save upload and download. Use that selected build’s export controls and keep a copy outside browser storage. Confirm that the downloaded file exists and record the build, website and export date alongside it.
Before moving from a current Mindustry build to a legacy build, check the project’s compatibility notes. A successful export does not guarantee that a different version or desktop client can import it. Keep the original backup unchanged while trying an import into a separate slot or profile when the game supports it.
Understand local storage and private browsing
Different domains and browser profiles normally have separate site storage. A mirror of the same game may not see progress saved on the original site. Private sessions, storage eviction and clearing site data can remove local progress; do not treat a browser tab as a backup.
Vice City may retain imported data in the browser, but keeping the original game archive is still necessary. Export progress separately if that build offers it. Reimporting game data alone does not restore a lost save.
Before changing devices
Check whether the exact game documents account sync or export/import. Transfer only the documented save format, keep both devices on compatible builds and verify progress on the new device before removing the old copy.
If no backup or sync method is documented, treat cross-device progress as unavailable until the project confirms otherwise. This directory cannot recover files or progress stored by an external game.
