====Block 13: Stats====
 +
This block has a constant length of 0x1724 or 0x173C bytes depending on the game version, and stores [[List_of_statistics_(GTA4)|various statistics]]; most of which can be viewed the game's Stats menu.
 +
To get the offset of a stat from its ID, multiply the ID by 4 and add the offset for Start of stats (0x54 or 0x6C).

===Checksum===
 
===Checksum===
−
After the last data block the checksum value goes. The checksum appears to be the sum of most of the bytes preceding it, however, which bytes exactly is unknown (See [[Talk:Saves_(GTA_4)#Block_32:_Checksum|discussion]]).
+
 
 +
The checksum follows the last data block.
 +
 
 +
* The <code>savegame size in bytes</code> in the meta data should be set to <code>1977922</code> (0x1E2E42), before calculating the checksum.
 +
* It is the sum of all the bytes preceding the checksum value.
 +
* Implementation Example: [https://pastebin.com/DvZPNDh5 A Python script] for calculating the checksum value
 +
 
 +
Note:
 +
* The reason is that the game adds the GFLW data size to the metadata after it has calculated the checksum.
 +
* The checksum value is ignored by the game. An incorrect checksum will not prevent a save file from being loaded.

The subject of this article is not fully documented yet. You can help by researching information about it and expanding this article.

This article deals with the format of a save game file for the PC version of GTA 4.

Location

1.0.8.0 IV / 1.1.3.0 EFLC and older

By default, the game places its save game files into the "%LocalAppData%\Rockstar Games\GTA IV\savegames\user_XXXXXXXXXXXXXXXX\" folder where XXXXXXXXXXXXXXXX is a 16-character string tied to the user's Games for Windows Live account.
Players using Xliveless or downgrade patches may find the save files in "%HomePath%\Documents\Rockstar Games\XXXX\savegames\" folder where XXXX is either "GTA IV" (base game), "TLAD", or "TBoGT".

1.2.x CE and newer

Save files for the Complete Edition can be found in "%HomePath%\Documents\Rockstar Games\GTA IV\Profiles\XXXXXXXX\" where XXXXXXXX is a 8-character string tied to the user's Rockstar Social Club account.

Save Slots

The save files themselves are named in the format "SGTA4XX" where XX represents the in-game slot number minus 1. There are 12 slots available in the game (1-12) plus additional auto-save slots (SGTA412 for the base game, SGTA413 for TLAD, and SGTA414 for TBoGT).

Format Details

  • Save file size varies but is typically just under 2 megabytes.
  • Byte order is little endian. For example, the number 3452 (0x0D7C) is represented as as 0x7C 0x0D.
  • A savegame consists of 32 data blocks, two blocks with metadata and a checksum number.

Savegame Metadata

A savegame file starts with this block, which has a constant length of 0x110 bytes.

OFFSET TYPE DESCRIPTION
0x00 dword savegame version number
0x04 dword savegame size in bytes
0x08 dword global variables size (?)
0x0C char[4] "SAVE" string
0x10 wchar_t[128] Name of last mission passed
0x110 end

Notes:

  • Savegame version number value is set under the [SAVEGAME_VERSION_NUMBER] section in the GTA IV/common/data/version.txt file
  • Last mission name is prefixed with either "TLAD - " or "TBoGT - " for Episodes From Liberty City saves

Data Blocks

Each data block consists of the 5 characters BLOCK followed by a variable amount of data; in general, each block has its own unique internal format. Following the BLOCK character is always a dword specifying the size of the block, starting at the beginning of BLOCK characters.

Block 0: SimpleVars

OFFSET TYPE DESCRIPTION
0x00 char[5] a "BLOCK" string

This block stores the relationship groups defined in Relations.dat.

OFFSET TYPE DESCRIPTION
0x0000 uint32 block size
0x0004 Relationships[70] Relationship groups
OFFSET TYPE DESCRIPTION

0x0018 uint96 ? bitfield
0x0024 uint96 dislike bitfield
0x0030 uint96 ? bitfield
0x003C uint96 hate bitfield

Note:

  • uint96 is a 12 byte (96 bits) integer.
  • The array index corresponds to the ped type, so array index 1 will be the relations for ped type 1 (CIVMALE)
  • The bits also correspond to the ped type, so the first bit in the bitfield will be for ped type 0 (PLAYER) and so on.

Checksum

The checksum follows the last data block.

  • The savegame size in bytes in the meta data should be set to 1977922 (0x1E2E42), before calculating the checksum.
  • It is the sum of all the bytes preceding the checksum value.
  • Implementation Example: A Python script for calculating the checksum value

Note:

  • The reason is that the game adds the GFLW data size to the metadata after it has calculated the checksum.
  • The checksum value is ignored by the game. An incorrect checksum will not prevent a save file from being loaded.

End Block

This block has a constant length of 0x16C bytes. Data in this block appears to relate to Games For Windows Live data.
