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 3.

Location

By default, the game places its save game files into the folder "GTA3 User Files" which is located in the current user's Documents folder. The location of this folder varies depending upon the version of Windows installed.

The save files themselves are named in the format GTA3sfX.b where X represents the in-game slot number. There are 8 slots available in the game (1-8).

Format Details

  • Save files are ALWAYS 0x3145C (201820) bytes long.
  • Byte order is little endian. For example, the number 3452 (0x0D7C) is represented as as 0x7C 0x0D.
  • File is divided into 20 blocks, followed by padding and then ending with a 4-byte checksum

Data Blocks

There is a DWORD value preceding any block of data which is equal to the size of the block.

Block 0: Miscellaneous

Game "meta-information" giving the overall state of things. Also includes 'TheScripts' sub-block.

Padding

Following the last data block is a variable amount of padding. Since every save file is exactly 0x3145C bytes in length this padding is necessary to fill the space between the data blocks which start the file and the checksum value which ends it. There could be up to 4 padding blocks, each one is up to 55,000 bytes in length.

Checksum

The final four bytes of a save file are an unsigned integer checksum value. This checksum is simply the sum of all the preceding 0x3145C bytes. If the checksum value does not match the calculated sum of those bytes, the game will consider the save file to be "corrupted" and refuse to load it. Thus, any time you make any changes to a save file you must remember to update the checksum when you are finished.
