About Auto save
Game data is saved automatically to slot 9 (SaveData09.sav) when Ayura returns to camp (the Abandoned Church).
AutoSaved data is overwritten every time.


About System Data
System data is saved as SaveData99.sav.
The following settings are taken from the system data, and will be initialized if the file is deleted.
When moving your saved data, we recommend moving the system data the Save folder as well.
 
Key Configurations
Key configuration settings are standardized throughout all saved data.
Key configuration settings are taken whenever you start the game or change maps.
If you delete the SaveData99.sav file, settings will be initialized.

Backups
Backups are automatically saved as numbers 20-29 in order of oldest to newest when Ayura returns to camp (the Abandoned Church).
There are only slots 1-9 on the loading screen, so in the event of loss of data, bugs preventing progress, or if you have forgotten to save the game,
you can rename the backup file with numbers 01-09 (e.g. SaveData02.sav) depending on the slot you wish to use.
(For the newest file, please refer to the update date of the saved data.)
In addition, even if the source file and the target file have different data, the data will be overwritten without fail.
