Watch_Dogs fat and dat archives

[namquang93]

This game's file structure is similar to Far Cry series with fat and dat archives, but a bit different. Here is an example, can anyone take a look into this. Hope someone can make a unpacker/packer for it, like Rick's tools. Thanks in advanced.

Code: Select all

Code: Select all

struct FATHeader
{
	DWORD	dwID; // 3TAF
	DWORD	dwVersion; // Always = 8
	DWORD	dwUnknown;
	DWORD	dwTotalFiles;
};

Code: Select all

struct FATEntry
{
	DWORD	dwHash;
	DWORD	dwSize;
	DWORD	dwZSize;
	DWORD	dwOffset;
};

PC > XMem
PS3 > Deflate
Xbox > XMem

It's just a modifed Xmem i think... well for pc at least I can see the magic header, here is a 010 editor script anyway for the fat files using what ekey found

Code: Select all

//--------------------------------------
//--- 010 Editor v5.0 Binary Template
//
// File: common.fat
// Author: EKey/Cra0kalo
// Revision: 1
// Purpose: WatchDogs
// ByteFormat - Little Endian
//--------------------------------------


typedef  float vec3[3];
typedef  float quat4[4];
typedef  string asciiz;

struct
{
   DWORD   dwID; // 3TAF
   DWORD   dwVersion; // Always = 8
   DWORD   dwUnknown;
   DWORD   dwTotalFiles;
}FATHeader;

//DWORD UnknownA;

local int i;
for(i = 0; i < FATHeader.dwTotalFiles; i++ )
{
struct
{
   DWORD   dwHash;
   DWORD   dwSize;
   DWORD   dwZSize;
   DWORD   dwOffset;
}FATEntry;


}

As for Xmem we can see the usual 0x0F 0xF5 0x12 0xEE magic identifier in the dat



Another script of a standard header it's obviously different but yeah I'm about to head to sleep will take a look tomorrow

Code: Select all

//--------------------------------------
//--- XCOMPRESS
//--- Watch Dogs 2014
//--------------------------------------
long Identifier; // # XCOMPRESS_FILE_IDENTIFIER_LZXNATIVE
long ContextFlags;
long Flags;
long WindowSize;
long CompressionPartitionSize;
long UncompressedSizeHigh;
long UncompressedSizeLow;
long CompressedSizeHigh;
long CompressedSizeLow;
long UncompressedBlockSize;
long CompressedBlockSizeMax;

xcompress.h

[Ekey]

PS3 compressed data header

Code: Select all

struct DataHeader
{
   SHORT   wChunksCount;
   SHORT   wUnknown; //xFF\x0F

  for(i = 0; i < DataHeader.wChunksCount; i++ )
  {
    Read(wChunksSizes, 2);
  }
};

Thanks to you guys I was able to extract the XCompress using quickbms , but there is a little modification to the file struct.

All big endian

Code: Select all

//--------------------------------------
//--- XCOMPRESS
//--- Watch Dogs 2014
//--------------------------------------
long Identifier; // # XCOMPRESS_FILE_IDENTIFIER_LZXNATIVE
long ContextFlags;
short Version;
short Reserved;
long Flags;
long WindowSize;
long CompressionPartitionSize;
long UncompressedSizeHigh;
long UncompressedSizeLow;
long CompressedSizeHigh;
long CompressedSizeLow;
long UncompressedBlockSize;
long CompressedBlockSizeMax;
long CompressedBlockSize;

I'll try to post the script , btw :I'm not good in writing scripts

How did you uncompress it? Does the game still work with uncompressed .dat files?
Might help with some performance issue many users have with the game.

[Haoose]

Does the game still work with uncompressed .dat files?

No. Need modified EXE-file for it

No. Need modified EXE-file for it

Not sure why that would be the case, the archive format supports uncompressed data just fine.

hello, will you work on this game ? I really love the way you did with Far Cry 3.

When I have the time.

Cool to see some progress! For me im wondering and am curious about the scripts, and if we are able to change them up depending on the code
