Protecting Your Save Data
Best practices for keeping your game saves safe.
3 min read
Your game saves represent hours of gameplay. Here’s how to protect them from battery death, corruption, and accidents.
The three layers of protection
1. Save Vault (automatic)
Playback automatically backs up your saves to the Vault:
- Saves every 5 minutes during gameplay (if changed)
- Saves when you exit a game
- Keeps up to 250 backups per game
- Stored on your computer, not the cartridge
This happens automatically with no configuration needed.
2. Autosave to Cartridge
When enabled, Playback writes saves to your cartridge whenever the game saves:
- Go to Settings > Playback
- Enable Autosave to Cartridge
This ensures your cartridge always has your latest progress, just like playing on original hardware.
3. Manual backups
For extra safety, create manual backups:
- Go to the Data tab
- Click Backup Save
- Save the file to a safe location
Consider keeping copies in:
- A cloud storage folder (Dropbox, Google Drive, iCloud)
- An external hard drive
- A different computer
When to be extra careful
Before replacing a cartridge battery
Cartridge batteries eventually die. Before replacing one:
- Back up your save with Playback
- Store the backup in a safe location
- Replace the battery
- Restore your save using Upload Save
When using reproduction cartridges
Reproduction cartridges often have unreliable saves. For these games:
- Disable Autosave to Cartridge (to avoid corrupting the cartridge)
- Rely on the Vault for your backups
- Back up manually after major progress
See Rewritable Cartridge Save Issues for more details.
Before using cheat codes
Cheats can corrupt save data. Before using cheats:
- Disable Autosave to Cartridge
- Create a manual backup
- Use cheats
- If something goes wrong, restore from your backup
See Cheat Codes for more details.
Recovering lost saves
Even if something goes wrong, the Vault has your back. Here’s how to recover from common scenarios:
Cartridge battery died
Your save is gone from the cartridge, but not from the Vault:
- Open the Vault folder for your game
- Find your most recent backup
- Replace the battery in your cartridge
- Use Upload Save to restore
Save lost while playing on original hardware
If your save was lost or corrupted while playing on an original console (power loss, cartridge bumped, etc.), you can recover it:
- Insert the cartridge into your Operator
- Open the Vault folder for your game
- Find a backup from your last Playback session
- Use Upload Save to restore
As long as you’ve played the game through Playback before, you’ll have Vault backups to recover from.
Accidentally overwrote a save
- Open the Vault folder for your game
- Find a backup from before the overwrite
- Use Upload Save to restore it
Save data appears corrupted
If a game reports corrupted save data:
- Try cleaning the cartridge contacts (often fixes read errors)
- If the issue persists, check the Vault for a working backup
- Use Upload Save to restore
Vault folder locations
| Platform | Location |
|---|---|
| Windows® | %LOCALAPPDATA%\Epilogue\Playback\vault\ |
| macOS® | ~/Library/Application Support/Epilogue/Playback/vault/ |
| Linux | ~/.local/share/Epilogue/Playback/vault/ |
Tips
- The Vault is your safety net. It’s always working in the background
- Manual backups to cloud storage add an extra layer of protection
- Check your cartridge batteries periodically, especially for old games
- Clean cartridge contacts regularly to prevent read/write errors
