Title: FF7 Crisis Core Extractor
Post by: G on 2007-09-25 19:07:04
Hi everyone.

I wrote extractor for FF7CC game data. Hope it'll be useful to many of you.
http://superg.org.ua/ff7cc_extractor.tar.bz2 (http://superg.org.ua/ff7cc_extractor.tar.bz2)

Usage:
1. Place game data files to "data" directory (files from PSP_GAME/USRDIR on game disc);
2. Run ff7cc_extractor for Linux, or ff7cc_extractor.exe for windows (there is two binaries in archive as well as source code);
3. Wait :), there is 1.6 Gb of files.

If anyone finds something about data formats used in this files, post here or PM me.

how do you guys go about learning how to decompress or extra datas from games?   I'd like to attempt to learn how to do this if theres any information on the net.

I just don't get how you guys are able to do all this not long after the games are released.

It takes almost 20 seconds to understand file system description format. It's pretty the same as in Xenogears.

So is there any way to learn how to decompress files form other games?   I don't know too much about programing and stuff but I learned some stuff so if there is any imformation on processes of figuring out how to decompress stuff can you give me a link.   I'd like to take a looks and do some research and see if its doable.

Jeez, they are using the same libs as Xenogears? Here I thought Square didn't re-use their code often. I guess what works, works.

Every file in game PAK has it's offset and size, all that needed to understand how record for it saved in index table.

Oh, it's just a simple obfuscation layer. That's why it's so simple.

How are we supposed to know what file is which?

Almost every extracted file has magic PSMF0014 at the beginning.
It's some kind of container format for PSP, I think.
There are also zero-length records before groups of file offsets [directories], I'll add them today or tomorrow.
Using directories It'll be easier to distinguish files by type.

It isn't actually a raw data, I've set this extension, because data formats isn't known yet.
For PSMF container there is some information on the net on psp video forums, but I think, that isn't a movie format, how they thinks, it's container format for all data for PSP.
I have not time now to work on this formats, need to finish FF7 AKAO :)

Any kind of update on this? I was hoping to get a look at the models and see if there are any characters there that shouldn't be....and port them to FF7 :-D

I don't plan to update this, this is only extractor, I'll only add directories support, as Akari requests.
Maybe in the future we'll work on data formats, who nows... :)

LOL
Well you can ask but there is the issue of someone doing it. :)
It's not like you are asking something easy to do.
Most people find those things a challenge however don't expect something for at least a week likely longer

Sorry for the bump but i was wondering if you would make an extractor for DC? I managed to find where the game stores all it's files and things so that should make it slightly easier on you.

The Russian group that translate Dirge of Cerberus found a way to decode the coded file
It's like a RAR files I don't know. In his patch show the directories of the engine that having been patched.

How it work please ? I've put my cc iso file in the data file and run ff7cc_extractor  but nothing ... :cry:
Title: Re: FF7 Crisis Core Extractor

you have to extract the data out of the ISO, use winrar or something.
Look for the files called "discimg.pkg" and "discimg.fse" and put them into the DATA folder of the extractor

If your image is CSO or ISO
use UMDGEN
