== import.db and title.db ==

With the introduction of the June update the folder structure changed slightly. You will now find "dbs" and "title" folders located in  /Nintendo 3DS/<SomeID>/<SomeID>/ along with the extdata folder. "dbs" contains two files, import.db and title.db. The purpose of the files in the "dbs" is to archive the list of titles installed on the SD card. These two files are only used for the management of SDMC installed 3DS Titles. The "title.db" file, archives the installed titles aswell as their, names, icons and size. The "import.db" also changes when a title is installed or deleted, but doesn't appear to contain info that the titles "title.db" does. Old and new of the "import.db" and "title.db" can be interchanged without any issues. Essentially the "title.db" acts as the DRM or access rights for downloaded SD card titles.

The "import.db" is used during the download/install of SD Card titles, and until the download is complete, it is the only file of the two which is modified.

'''"00000001.sav"''' - This is the title's encrypted savegame. Although these saves look similar to FLASH savegames, these savegames use proper unique CTR for each AES block in the file, and the CTR properly changes for each savegame write. Renaming these savegames causes home-menu to hang while launching titles, modifying saves throws the usual checksum/hash corruption like gamecard flash saves.
