| For all these packages, data starts at offset 0x4000 and is not console-unique. This is installed from "package2" in firmware package A (0100000000000819) by default. With the exFAT update installed, this is switched to firmware package C (010000000000081B). The data stored here matches the raw /nx/package2 file stored in the 81[9AB] data archives -- there is no additional encryption. "BCPKG2" is "BootConfigAndPackage2": for example, from [[Factory_Setup|SystemInitializer]]: "BootConfigAndPackage2Part1".

The filenames for saveimages is just "<lower-case hex u64 saveID>". SYSTEM-partition saveIDs are specified by [[Filesystem_services|FS]] commands, while USER-partition saveIDs are determined by FS-module internally. The high u32 of the saveID is normally either 0x00000000 or 0x80000000.

Encrypted partitions use AES-XTS using the same non-standard (endian-swapped) tweak as other Nintendo AES-XTS code, initial_sector == 0, and sector size 0x4000. All encrypted partitions use console unique keydata.
