Which archive formats does PSP know?

Hallo all together!
I would like to take some graphics out of a PSP Game for my new WinAmp Scin!
But unfortunatly all the data of this game is stored in a big archive file,
so I need to extract files from it first (archive is in USRDIR).
So this is my question:
Are there many archive types, that psp "understands", and which are these?
This archive I need to open consists of two files. One is very small (~200kb) and the other very big (small one stores directory informations for the big one, I guess).
AND I've opened these files in a hex editor and there is a header (archive identity string - the first 4 bytes) at the beginning of the big one.
It says "Atel". Any idea which archive type that could be?
It's also possible that its not really just an archive but a disc image. Are there any image formats consisting of 2 files with the "Atel" header in the big one?

I would be very happy to open this thing.
If you don't really know anything about this specific archive type,
but you have information on all the archive types that can be used for PSP,
please feel free to post them here, so I can try out each of them )

Thank you

Well there is a zip library, and plenty of C source on the net.

@Art:
Well, yeah, thats right! But the problem is, that too many different archive types are out there, so I hope to shrink their amount by asking, which are used on psp =)

Still thank you! Using search engine with "zip library" I've found an interesting archive format :) Trying it out now

More than likely it's something specific related to that game's requirements, not something in the PSP OS. You may need to examine the game code to work out how to unpack it.
Isn't there some screengrab software out there?
