When creating the SD savedata, the application generates a random u64 value, then stores it in an arbitary savefile in the savegame FS. The application then uses the anti-savegame-restore [[Filesystem_services|FS]] commands to verify the stored u64(with the u64 loaded by FS module), and to update the u64 used by FS module. The u64 used by FS module is stored in a NAND savegame.
 +

Each time the application writes to the savegame, the u64 value stored in the savefile should be updated(and the command for updating the NAND u64 value should be used as well). Usually applications update this value by incrementing it, however generating a new random-number or other methods of updating it can be used as well.
