305w ago - Had a little time over the weekend to play with some PS3 .PKG files.
Here is a peek inside a PS3 Package file, see below!
For reference, some files like executables are still encrypted even when unpacked from a .PKG file, sound files are not. PSARC files are definitely compressed and likely encrypted as well.

to see what there is into LEMMING ACTIVATION [133kb] or SUPERRUBADUB FULL ACTIVATION[100kb]. i know that now the activaction is changed but maybe this little file can be more easy to understand. (this file must write some data on hd)
Ya, he won't be able to tell you how it's unpacked, because as you reiterated what I stated above... it is done via Debug/TEST PS3.
Beyond that, I don't know what you're asking... if you have a file you would like CJPC to try unpacking with his Debug unit then attach it perhaps, but he is really busy and so I wouldn't expect a fast reply.
