If the client process lacks the relevant permission for any of the above partition IDs, error 0x2EE202 is returned.

[[NCA]]s stored in NAND are raw, identical to the data readable with [[Content_Manager_services#ReadEntryRaw]].

The filenames for saveimages is just "<lower-case hex u64 saveID>". saveIDs aren't related to the titleID, or at least not for USER-partition saves. The high u32 of the saveID is normally either 0x00000000 or 0x80000000.

Used for accessing data calibrated at the factory. Probably only for console-unique data?(Everything read so far has been console-unique)

== GetDeviceCert ==
Takes a type-0x16 output buffer with fixed size 0x180.

Returns the DeviceCert. This is identical to 3DS DeviceCert/CTCert besides the strings. NIM loads the DeviceId from this.

== GetDeviceCert2 ==
Takes a type-0x16 output buffer with fixed size 0x240.

Same as GetDeviceCert, except this returns more data and the data starts differing at offset 0x108 compared to GetDeviceCert.

== GetTLSClientPrivk ==
Takes a type-0x16 output buffer with fixed size 0x134.

Returns a container-structure for the encrypted TLS client-privk. Decrypting this fails unless an unknown size >0x134 is passed to this setcal cmd?

Used by SSL-sysmodule, see [[SSL_services|here]].

== GetTLSClientCert ==
Takes a type-0x16 output buffer with fixed size 0x804.

Returns a container-structure for the plaintext TLS client-cert.

Used by SSL-sysmodule, see [[SSL_services|here]].

| Userland ARM undefined instruction exception
|-
| 2168-0001
| Userland ARM prefetch-abort due to PC set to non-executable region
|-
