Save guide

Battery saves vs save states in SpatialEMU

Battery saves are data written through a game's original save mechanism, while save states capture a broader snapshot of emulator runtime state. Save states can be more sensitive to emulator-core and app-version changes. Keep backups of important saves and do not assume either format synchronizes automatically across devices.

Steps

How to proceed

  1. Use the game's own saveCreate a battery save when the title supports it.
  2. Create save states deliberatelyUse states for convenient checkpoints, not as the only long-term backup.
  3. Label and testConfirm that a state loads before relying on it.
  4. Back up important dataUse your preferred operating-system backup workflow.
  5. Re-test after updatesCore or app changes can affect save-state compatibility.

FAQ

Common questions

Which save type is more portable?

Battery saves are generally closer to original game behavior, but portability still depends on the emulator and file format.

Do saves sync across devices?

SpatialEMU does not currently claim verified automatic cross-device save synchronization.

Can an update break a save state?

Save states may be sensitive to core and app-version changes, so keep separate backups.
