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

Location

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.

The save files themselves are named in the format SGTA4XX where XX represents the in-game slot number. There are 12 slots available in the game (1-12) plus an additional auto-save slot (SGTA400).

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
0x04 dword size of block in bytes (always 0xB9)
0x09 dword start of data; see below
SimpleVars
OFFSET TYPE DESCRIPTION
0x00 byte[32] unknown data
0x20 dword length (ms) of in-game minute
0x24 dword weather timer (?)
0x28 dword in-game month
0x2C dword in-game day
0x30 dword in-game hours
0x34 dword in-game minutes
0x38 dword in-game day of week
0x3C byte[116] unknown data
0xB0 end

Block 1: PlayerInfo

This block has a constant length of 0xD4 bytes.

OFFSET TYPE DESCRIPTION
0x00 dword Size of block
0x04 byte[18] unknown
0x1C dword Player money
0x20 byte[4] unknown
0x24 dword Player money (Again. Perhaps one is amount shown on screen.)
0x28 byte[172] unknown
0xD4 end
