I have just finished new little scripts for http://www.sweetscape.com/download/010EditorInstaller.exe to decode / display / edit PS3 Update Files (PUP) and SELF files.
It is a work in progress and these scripts are not final script and contains lot of unknown things.
Download: PS3 PUP File Decoder Script v0.1 / PS3 SELF File Decoder Script v0.1
For 010 Editor beginners, see the 010 Editor how-to HERE.
Finally, feel free to add any findings to the http://ps3hvdoc.wikispaces.com/.
