A. 1. Check app permissions: Ensure that PPSSPP has the necessary permissions to write to storage. Go to Settings > Apps > PPSSPP > Permissions and enable any relevant permissions. 2. Clear app data: Go to Settings > Apps > PPSSPP > Storage > Clear Data. This will reset the app, but you will lose any saved settings.

B. 3. Reinstall the app: If settings still refuse to save, uninstall and reinstall PPSSPP. This can resolve any underlying issues preventing settings from being saved.
