97w ago - I have done this PS3 PUP Unpacker & Decrypter v2.2 homebrew application tool (basically is an script that use other tools) a long time ago for easily unpacking a PlayStation 3 PUP file for those who don't know how. This works on Cygwin and Ubuntu (not CMD windows)
-h, --help displays this help
-x, --un-pup unpack PUP files only
-e, --un-tar unpack update_files.tar of PUP only
-c, --deun-core decrypt and unpack Core_OS of PUP file only
-t, --deun-tar decrypt and unpack TAR files of PUP only
-p, --deun-pkg decrypt and unpack all PKG files of PUP only
-s, --de-self decrypt all SELF files of PUP only
-i, --de-index unpack and decrypt index.dat of PUP only
-v, --conv-vag unpack and convert VAG to WAV files of PUP only
-r, --deun-rco decrypts and unpack RCO files of PUP only
-all, --deun-all unpack and decrypt entire PUP files
1) Unpack folder of RAR on your home directory in Cygwin (C:\cygwin\home\XXXX\Unpacker)
2) Copy PS3UPDAT.PUP file you want in it
3) Open Cygwin's console and enter the folder
4) And type: (OFW_355 is an example, you can change this)
5) Now depending what option you had choosen the executable will do it all automatically
All is done, "dev_decrypted_unpacked" folders contain self decrypted files
This program requires certain exe files and PS3 keys that are included in RAR, DON'T DELETE THEM. If an error occurs it will stop automatically, showing what has happened. Hope this helps someone
