When managing 3DS Software installed to the SD Card, the [[Title Database|title.db]] is read by the core receiving [[Application Manager Services PXI|AM]] commands. From the title.db file, AM gets a list of installed titles, title sizes and the name of the ".cmd" file for each title, which is used to check the authenticity of the title data(product code, title version, and if an electronic manaual is used, is also kept for each title, in the title.db, but won't be used by the Data Management Utility). For each title listed, it checks if the title is authentic(via the .cmd file). If the title passes authentication, Data Management decrypts/reads the ICN data from the executable NCCH([[CXI]]) and displays it along with the archived title size. If a title doesn't pass authentication, a placeholder icon(light grey with a '?' in the center), name ('????????') and a size of zero are used. Deleting titles removes the title data from the title.db and import.db, and deletes the directory of the content. | When managing 3DS Software installed to the SD Card, the [[Title Database|title.db]] is read by the core receiving [[Application Manager Services PXI|AM]] commands.

Additionally, if a CTR-NAND or TWL-NAND installed title passes authentication, but has a fake-signed ticket, System Settings will call "[[SVC|svcBreak]]" upon entering Data Management -> 3DS | DSiWare. Barring patched RSA sig checks, this will prevent a user from viewing the 3DS and/or DSiWare Data Management menu depending on which NAND(s) the offending title(s) is installed. This phenomenon has been known to lock users out of executing widely used exploits like [https://github.com/zoogie/Bannerbomb3 Bannerbomb3], which need access to Data Management to trigger. | |||
