Gray Matter PAK

Post by Gocha » Wed Nov 17, 2010 4:16 pm

Hi guys,

There is out one nice adventure Gra Matter, so it is available only in English and Deutch.

Here are localization files, looks like compressed somehow.
en.pak, 171 kb: http://www.datafilehost.com/download-7c1ecb66.html
Fonts.pak, 658 kb: http://www.datafilehost.com/download-605ac977.html

Any help with extracting/decompressing and back, will be appreciated.

Thanks in advance my brothers! Love you!
My great respect and appreciation for them, who research game files! Special thanks to: aluigi, bacter, DerPlaya, Rick, Turfster, twig, Zench. Sorry if someone is missing in my list, I'll update when I'll notice it again

Here's my .PAK extractor / packer / replacer program.

The attached file deleted. See my latest comment for the most recent version...

Hello, here the file spec, sorry but i don't know correct wiki-xentax file format or bms scripting.

File extension: .PAK
Endianness: Little-endian

Format Specifications

Code: Select all

uint32 {4}		- Unpacket Size of Header

uint32 {4}		- Offset Base

byte {Offset Base - 8}	- Header (compressed in ZLIB)

byte {x}		- File 1 (compressed in ZLIB) (Located in Offset Base)       

byte {x}		- File 2 (compressed in ZLIB) (Located in Offset Base + Offset)

....

byte {x}		- File x (compressed in ZLIB) ...
Header Spec (unpacked)

Code: Select all

uint32 {4}		- Num Subdirectories

FOR 0 to numsubdirectories - 1

	uint32 {4}	- Strlen Directory Name
	
	char {strlen}	- Directory Name
	
	uint32 {4} = 0	- NULL
	
	uint32 {4}	- Num Files

	FOR 0 to numfiles - 1

		uint32 {4} 	- Strlen Filename

		char {strlen}	- Filename

		uint32 {4}	- Offset (relative)

		uint32 {4}	- Zsize (compressed size)

		uint32 {4}	- Size (unpacket size)

 	FOREND
FOREND

uint32 {4} = 0		- NULL
In Depth *.LOC Spec (unpacked - Located in LOCALIZED\xx.pak)

Code: Select all

uitn32 {4}						- Number of strings

FOR x = 0 to numstring

	uint32 {4}					- Relative offset String X

ENDFOR

char{offset1 - offset0} 				- String 1 (null terminated)

char{offset2 - offset1} 				- String 2 (null terminated)

...

char{sizefile - 4*(1 + numstring) - Last offset}	- Last String (null terminated)

Good work, just a small correction:

	uint32 {4}	- Strlen Directory Name
	
	char {strlen}	- Directory Name
	
	uint32 {4} = 0	- NULL
The last zero value is presumably the number of subdirectories within the current directory. The whole structure is most probably recursive.

 [...]

This last value should be the number of files in the current directory, otherwise you'll miss some files. Take a look at PAK archives that don't have subdirectories (fonts.pak?) and you'll see what I'm hinting at.

In the end, the basic structure should look like this:

Code: Select all

TPAKStruct = (
  uint32 {4}     - number of subdirectories
  // for each subdirectory
    uint32 {4}     - subdirectory name length
    char {x}       - subdirectory name
    TPAKStruct {x} - recursive entry for subdirectory
  uint32 {4}     - number of files within this directory
  // for each file: just as you described
)
Best wishes,
Deniz

mmm... great I had not thought about it

Yep, i missed add this note in file spec for files without directories. And another "bug" was For 0 to numfiles -> must be For 0 to numfiles - 1 ^_^

TPAKStruct = (
  uint32 {4}     - number of subdirectories

    uint32 {4}     - subdirectory name length
    char {x}       - subdirectory name
    TPAKStruct {x} - recursive entry for subdirectory
  uint32 {4}     - number of files within this directory
  // for each file: just as you described
)
Better than mi looooooong file spec jajaja. I'll take note !!!
Best wishes,
Deniz

I almost finished my tools too, I'll post them in a few hours. Deniz Oezmen is right, it's recursive. I'm adding support for XBOX360 files and there is a little dumper/reinserter for the text files (:

Can anyone help me with the format of .abc and .fnt files in fonts.pak?

Here's a simple commandline version of my PAK maker/extractor/updater.

Could someone post some XBOX sample .pak files?
It's possible that it's just the same structure as the PC version, with reversed Endianness.

Quoting this in case there's someone here who can help. I ready to start translating the game but need to add some of the characters typical to our language.
