The data it's compressed i dont' know wich compressor it's used.
Maybe it's zlib?.

Here it's the sample:

Scanned thru the archive and found some 16x16 PNG pictures.
, also found 256x256 and 512x512 PNG images.

however, the images larger than 16x16 is not viewable,
they have a strange header ive never seen before in a PNG image,
but they are for sure PNG images.
those do not look compressed. but there is a possibility that the
rest of the files in the archive is compressed yes =o

an example, on all 16x16 PNGs they have pHYs Header,
on 256x256 and up this header has been replaced with a
ICC Profile header. and the IDAT (image data) is far away down in the
image file, where on the 16x16 images are located in the beginning of
the file. could be a custom made PNG format.

keep in mind that PNG format is automatically compressed in its
whole structure. so compressing an PNG picture with rar or zip
does not make any sense.

i would like to have the full archive so i can check it in whole.
because from what i see now, jaeder naub ripped out exactly 1 MB
of PNGs from this front* archive. (and the cutted files was 1 MB)

BUT.....the back* cut is a little different. there are only 1 PNG file
12kb big and the rest is an unknown file for me.

im still investigating. what confuses me most is this odd PNG header
for some of the files.

Looks like a zip, but it's not a zip, maybe a own packer?

Whatever it is, it's no known WinRAR archive format. Usually, opening pak files in WinRAR will open them in case WinRAR recognizes the format. In this case, WinRAR doesn't. ;)

Pulposo:
Okay, the whole archive is actually compressed, except for the PNG images =o , but everything else is indeed compressed.

Managed to get a wav file out of the GlobalEK.pak file seemed to play ok,

I assume the first 4 chars are the identifier (if that is the word)

seems strange thou that all the map .pak files start PAKC and the GlobalEK.pak file starts PAKA.

Could just be me not having a clue what i'm looking at thou :(

PAKC it's compressed, PAKA not.

Sorry, i only tested with the files, if you compress the packa file with rar the compression it's good, the pakc no.

I know it's silly and easy but works. :P
