Editing Playstation Update Package (PUP)

[[Category:Software]]<noinclude>[[Category:Main]]</noinclude>
= Details =
The PS Vita and PS Vita TV OS can install the update as PSP2UPDAT.PUP or as PSVUPDAT.PUP.<br />
(thanks Math, for this information.)<br />
The update that comes from 
<pre>
http://djp01.psv.update.playstation.net/update/psv/image/image/<YYYY_MMDD>/pre_<md5>/PSVUPDAT.PUP
</pre>
is only used by sony on the website; that's why there is no update list on that server.

= Extraction =
The PS Vita & PS Vita TV update files can be extracted using:
* "[http://www.vitadevwiki.com/index.php?title=Tools PS VITA Firmware xTractor]"
* pupunpack from [http://www.vitadevwiki.com/index.php?title=Tools#Vitatools vitatools].

= Decryption =
<!-- To decrypt the files which are unpacked using the tool, the key is available under PS Vita Keys -->
Unknown for now.


== Structure ==
The file structure of the Vita's PUP files is almost identical to the PS3's, although there is a slight difference in the header and the hash algorithm. For starters, whereas in PS3 the format was big-endian for the Vita it has been switched to little endian (probably the same for all Vita formats). Also the '''Package Version''' field in Vita pups is set to 2 where in PS3 updates it was set to 1. There is also 0x50 bytes of extra data in the header and the hashes used are of a longer length than in PS3 updates (0x20 bytes in Vita vs 0x14 in PS3)

== Header ==

=== File Table ===
The file table consists of a number of file entries determined by '''File Count''', with the format below (which is the same as the format in PS3 PUP1 files)

==Hash Table==
The hash table contains a hash entry for every file inside the PUP.

The hash entry format is:

= Regioning =
If simular to PS3, then there is no regioning in the .PUP files, they are the same for all different regions.<br />
The PS Vita however gets the psp2-updatelist.xml from different servers, depening on the region of that model.
