378w 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.

Short answer is no, since I can not install or unpack a retail PKG, I will not be able to look inside one of those activation pkg's.

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.

I dont want unpak some .pkg file, i ask if CJPC can unpack an activation file.

and if know how this file is unpacked, maybe the answer can be "i don't know because TEST/DEBUG ps3 do it" ?

He already explained this above... did you not read? It's an app used on a Debug/TEST PS3... so no, you can't do it yourself.

(like this for lemming http://zeus.dl.playstation.net/cdn/EP9000/NPEA00004_00/wCgJ2cjPbQxUSgB1YB83a7CLQpPBQX2wM87BlRqYUiBQPhqRWKA5uNeS9AIrmAUEQogrEwejbdD9bCDgbvIiWWogdQBQOxJN6s8RY.pkg?product=0085&country=us)

Just wondering, since you can upack one, why can't you pack one with different files inside? can this be done with retail pkgs? Thanks, and also any updates on the Keyvault project, i think everyone is keen to know! :-)

AND thanks for all the hard work!

where can we get this program? i mention ps3unpkgr. is it homebrew (opensource) program? i assume (since it has not any extension), that it is not a sony-signed .self.

sorry, cjpc. but what is the program to unpack .pkg? or you unpack them individually by hands?
