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 is represented as as 0x7C 0x0D.
- File is divided into 22 blocks, followed by a 4-byte checksum (more info on the checksum below).
Data Blocks
There is a DWORD value preceding any block of data which is equal to the size of the block.
