Since NAND applications store save data to system memory, a NAND application can read and write save data from another NAND application.
The NA_LoadOtherTitleArchive function will load save data of a specified NAND application as an otherPub or otherPrv archive. By using the FS library to access these archives, you can access save data of the specified NAND application.
The NA_LoadOtherTitleArchive function can only load a single save data region at a time. To access both public and private save data, or to access save data for multiple NAND applications, unload save data regions with the NA_UnloadOtherTitleArchive function each time you access a single save data region.
Only NAND applications can access save data from other NAND applications.
The NAND application sample demo other_backup reads and writes save data from another NAND application (the backup demo).
The other_backup demo is in the $TwlSDK/build/demos.TWL/nandApp/other_backup folder. The backup demo is in the $TwlSDK/build/demos.TWL/nandApp/backup folder.
