SD Savedata Backups

From 3dbrew

Introduced in 6.0.0-11, users are able to backup savedata for titles installed to SDMC, to a maximum of 30 'slots'. Users can backup savedata while in the Home Menu, available as an option when selecting an application. In System Settings, user are able to backup, restore and delete savedata backups. There are however, restrictions.


Savedata backups are located in the directory:

sdmc:/Nintendo 3DS/<ID0>/<ID1>/backups

The savedata backup directory structure(this structure is repeated for every slot):

    └───<Application TitleID>

  • XXX - A three digit hexadecimal number representing the slot number i.e. (000-01d).
  • <Application TitleID> - This directory contains a verbatim backup of files in the title's "data" directory(where the save file is located).

There can only be one savedata per slot, and details about the slots are recorded in Backup.dat and hence cannot manually be created. For recovery reasons, if Backup.dat is damaged, details about the backup slots will be recreated from the files in the backup directory.


Some titles are restricted in how their saves are backed up. These restricted saves can can only be backed up when the title is deleted and can only be restored once. GBA titles however are not allowed to be backed up at all, the reasons for this are unknown. This restriction is triggered if a certain flag in the title's icon is set. Or if the SaveID of the title is located in the ctr_backup_black_list file in the NS CFA, which is practically a Unique-ID blacklist. The titles blacklisted in the ctr_backup_black_list, are:
