Here's why:
PKG's are SIGNED with a Sony key. If you attempt to edit the file, it must be resigned. Say you do know the key. If you do, then why are you attempting to edit a PKG? You could just decrypt the HDD, then edit the file on the HDD. You could do much more than that, even, including making your own custom firmware which supports extracting game data to a USB Drive. Anyone who ACTUALLY thinks they have done anything with PKG's is wrong. Seriously. People with Debug/Test PS3's with all those extra debugging features can't even do anything with them. If you think that looking at these files in a hex editor is going to do anything, it won't.
Just a little something to prevent people from getting false hope.
I'm probably wrong about some of this, but I do KNOW that PKG's are signed and can't be edited in any way shape or form.
Stop distracting us, My team has already gotten this all done. Decompressed, and now compressed. Good luck. Have fun believing this guy ^^ -- Just know who told you.
