I know there are MPQ editors and extractors BUT they all decode the included adpcm files into raw PCM. Which is not what I'm after. I'm searching for a way to simply decompress the MPQ archive and extract the raw contents.
Here's an example: https://mega.nz/#!2tVjzSKC!7GBu5nX1r5Cl ... 4R7xJGBlQ0
Would be a blast to finally get my hands on the REAL files rather than the pseudo files!
Thanks for your help!

Since you are a script maker, here is the format structure: http://www.zezula.net/en/mpq/mpqformat.html

i'm not sure how you'd expect him to write a script based on that format

if anything else though i'll just leave this here

Why not? As you can see in this thread, I don't believe he will have any difficulty...
About StormLib, the home site of this lib is the one I pointed: http://www.zezula.net

Well, the problem with that file is that it's compressed or encrypted, I hope the first. I haven't been able to find the decompression type, so I'm asking for help here. The first link doesn't say anything about a compression, so I'm at a loss here...

Quick look at your file, we can see that it is an MPQ format version 1, so there's no HET and BET table, only the HashTable and BlockTable, both are encrypted, look in Fundamentals for informations about hash theory, after decrypted you'll able to read the Flags that determined if the blocks/data are encrypted or compressed and what compression method is used.

Wow, well... that really surpasses my experience to be honest. I'd be glad if somebody could do this for me. Sorry for sounding lazy but it just doesn't seem worthwile to get into all that theory just to be able to get these files. :( So.... pretty please? ;)
