ID0 is the first 0x10-bytes from a SHA256 [[nand/private/movable.sed|hash]] and ID1 is generated from the SD card CID.

Title data stored on the SD Card is encrypted with the console-unique [[nand/private/movable.sed|keyslots]], whereas NAND title data is stored as cleartext.

Title data stored on the SD Card is encrypted with the console-unique [[nand/private/movable.sed|keyslots]], however the NAND title data is stored as cleartext.
      
The base CTR for files stored under /title is likely based on the /title path, similar to extdata. This base CTR is unique per titleID and filename. The base CTR never changes after creation of each file.

When a newer version of a title is installed, the new .app content, .tmd, and .cmd(and .ctx for NAND titles) are written to the /title directory, however the old files here are not yet deleted. Once installation of the title is [[AMNet:InstallTitlesFinish|finalized]], the info from [[Title_Database|import.db]] is moved to [[Title_Database|title.db]] so that the system uses the newer files instead, then the old /title files are deleted.
