By default, GTA SA places its saved game files into the folder "GTA San Andreas 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. Some typical locations for a user with an account named "Fred" would be:
−
* C:\My Documents\GTA San Andreas User Files -- Windows 98 Example
+
* <code>C:\My Documents\GTA San Andreas User Files</code> &ndash; ''Windows 98'' Example
−
* C:\Documents and Settings\Fred\My Documents\GTA San Andreas User Files -- Windows XP Example
+
* <code>C:\Documents and Settings\Fred\My Documents\GTA San Andreas User Files</code> &ndash; ''Windows XP'' Example
−
* C:\Users\Fred\Documents\GTA San Andreas User Files -- Windows Vista Example
+
* <code>C:\Users\Fred\Documents\GTA San Andreas User Files</code> &ndash; ''Windows Vista'' Example
−
Obviously those locations can vary based upon different Windows configurations or installation options. Note also that the executable can be modified to use a different file location through the use of a hex editor and special registry key in a process outlined at [http://www.gtaforums.com/index.php?showtopic=194371 GTAForums]

The save files themselves are named in the format '''GTASAsfX.b''' where '''X''' represents the in-game slot number. So, the game saved in slot 1 will be stored in the save file '''GTASAsf1.b''' and the game saved in slot 5 will be stored in the save file '''GTASAsf5.b'''. There are 8 slots available in the game (1-8). GTASA save files are always 0x31800 bytes long (202,752 in decimal) and are not compressed or encoded in any way.

Note that many of the blocks contain data structures. These structures are aligned along 4-byte boundaries; thus if there's a field with size 1 or 2 bytes in the end of structure, there are also additional unused bytes present at the end of the structure which pad it to fill the remaining space. This type of gap can also occur in the middle of a structure. The convention used by this article is to mark such gaps as an array of bytes with the description '''(Align)''' .

# Version 2.0 of GTASA will not load a save file if the Version ID String does not match its own Version ID String. Thus if a game was played on a version 1.x exe using the exact same set of mission scripts as a version 2.0 installation, the version 2.0 game will refuse to load the save unless this ID is changed.

Information pertaining to the [[:Category:Mission_Scripting|Mission Scripts]] in use when the game was saved. Includes all global variables and information about running threads including thread pointers and local variables. A minor size difference between the MAIN section of the version 1 and version 2 scripts is the primary cause of incompatibility between version 1 and version 2 saves because it forces the other threads to be at slightly different memory locations. One can adjust the thread pointers in this block and (if converting from 1 to 2) the Version ID String from block 0 to convert a save between the two versions; this applies to either completely unmodded or identically-modded installations of v1 and v2.

Via [[:Category:Mission_Scripting|mission scripting]] it's only possible to create a first kind of such object (static) - using opcode [[0363]], so normally the 'type' parameter is equal to 2.

Notes:
−
# Police trigger zone is a special zone consisting of 3 rectangles. When player drive into the first rectangle (defined by 2 ends of the rectange diagonal set by the first 2 XY pairs) having a certain wanted level (depends on the 'type' field), two police cars appear there: one in the second rectangle, the second car in the third rectangle. These rectangles are defined in the same manner as the player's one.
+
# Police Triggers are a special zone consisting of a rectangle defined by 2 ends of the rectangle diagonal, and two rays defined by a starting point and point along the ray indicating the initial direction of travel.
−
# Trigger zone can be created using opcode [[04F8]]
+
# When the player is in the police trigger rectangle and meets the requirements of the police trigger type, then a cop will spawn at the endpoint of ray A headed in the direction of the 2nd defined point.
−
# Trigger zone is activated only once per 40 seconds (the first field is used to control this).
+
# If the police trigger type includes 2 police, then a cop will also spawn along ray B.
 +
# The police are not bound to continue in the specified direction after their initial spawn.
 +

New enex connections can be added to the save after the save is created if temporary (burglary) connections are not present (indoor or isolated saves). The flags and links for existing connections will not be updated by changes in the IPL file. If the enex structure is removed from the block (except for the -1 terminator) the game will remap all connections based on the current IPL configuration.

0x000 Structure[14]  -- see details below
+
This block contains data relating to various radio stations. The bulk of the block is an array of data structures for each station. Not much is known about these structures currently but part of the data seems to be a record of which tracks have played recently. Following this array of structures there is a collection of byte flags which are related to high-number player Stats. These Stats are used to trigger different episodes and radio clips throughout the game. Note that the "set by" comments refer to missions in the original, unmodified game and they can obviously be set at different times instead.

The final four bytes of a save file are an unsigned integer checksum value. This checksum is simply the sum of all the preceding 0x317FC 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.

This article deals with the format of a save game file for GTA San Andreas. It is specifically geared towards the PC version(s) but much of it may be applicable to console versions too.

Location and Format Overview

By default, GTA SA places its saved game files into the folder "GTA San Andreas 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. Some typical locations for a user with an account named "Fred" would be:

  • C:\My Documents\GTA San Andreas User Files – Windows 98 Example
  • C:\Documents and Settings\Fred\My Documents\GTA San Andreas User Files – Windows XP Example
  • C:\Users\Fred\Documents\GTA San Andreas User Files – Windows Vista Example

Obviously those locations can vary based upon different Windows configurations or installation options. Note also that the executable can be modified to use a different file location through the use of a hex editor and special registry key in a process outlined at GTAForums or use Save Game Path Editor

The save files themselves are named in the format GTASAsfX.b where X represents the in-game slot number. So, the game saved in slot 1 will be stored in the save file GTASAsf1.b and the game saved in slot 5 will be stored in the save file GTASAsf5.b. There are 8 slots available in the game (1-8). GTASA save files are always 0x31800 bytes long (202,752 in decimal) and are not compressed or encoded in any way.

Format Details

A GTASA save file consists of 28 "blocks" of data followed by some duplicated data for padding and then ending with a checksum value. Each of these elements is described below.

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. The format descriptions in this article only deal with those internal block formats which follow the initial BLOCK identifier and all offsets start at the byte following the BLOCK identifier for the given block.

Note that many of the blocks contain data structures. These structures are aligned along 4-byte boundaries; thus if there's a field with size 1 or 2 bytes in the end of structure, there are also additional unused bytes present at the end of the structure which pad it to fill the remaining space. This type of gap can also occur in the middle of a structure. The convention used by this article is to mark such gaps as an array of bytes with the description (Align) .

Block 0: Simple Vars

Notes:
^ Version 2.0 of GTASA will not load a save file if the Version ID String does not match its own Version ID String. Thus if a game was played on a version 1.x exe using the exact same set of mission scripts as a version 2.0 installation, the version 2.0 game will refuse to load the save unless this ID is changed. Version 1.x exes make no Version ID String check and will attempt to load any non-corrupted save. Some known Version ID String values (listed as consecutive bytes):

  • 0x75 0x81 0xDA 0x35 -- Version 1.00 Unmodified EXE
  • 0x83 0xE5 0xF3 0x65 -- Version 1.00 Modified EXE
  • 0x58 0xBE 0x6E 0x9A -- Version 1.01 Unmodified EXE
  • 0x5E 0x76 0x45 0x93 -- Version 1.01 Modified EXE
  • 0xF6 0x8D 0x14 0xFD -- Version 2.00 Unmodified EXE
  • 0x22 0xCC 0x31 0x5D -- Version 2.00 (German)
  • 0xF6 0x8D 0x14 0xFD -- PS2 Version 2 (Greatest Hits)
  • 0x4C 0xDC 0x1D 0x64 -- PS2 Version 1 (Original Edition)

^ While the save name can be changed here to pretty much anything, that name will not persist the next time the game is saved, even if no missions were completed during the play session. This is because each time the game is saved this name string is reset based upon the GXT entry for the Last Mission Passed key stored in Block 16.
^ Time copy flag shows whether the time data was saved using opcode 0253.
^ Chaos is a value need to be gained to get one more star. MaxChaos is a limit for current wanted level.
^ When the censore flag is set to 0, some actions are disabled in the game, such as money drop from the killed people, no more headshots, etc. This flag is controlled by what language you are using. If it's English, this flag is set to 1.
^ This is a number of how much times the cinematic camera help (about switching display modes) will be shown. Initially this value equals to 2. When it reaches zero, the help does not appear on cinematic camera enabling.
^ This is a flag, which is set to 1 when player first time stealing a vehicle and get a help message about it, to prevent displaying this message again.

Block 1: Script

Information pertaining to the mission scripts in use when the game was saved. Includes all global variables and information about running threads including thread pointers and local variables. A minor size difference between the MAIN section of the version 1 and version 2 scripts is the primary cause of incompatibility between version 1 and version 2 saves because it forces the other threads to be at slightly different memory locations. One can adjust the thread pointers in this block and (if converting from 1 to 2) the Version ID String from block 0 to convert a save between the two versions; this applies to either completely unmodded or identically-modded installations of v1 and v2.

As the first section in this block can vary in size, offsets given are from the current section.

InvisibleObject
  0x00  dword          type

Block 3: Garages

Information defining all garages (including bomb shops, pay & sprays, etc.) and also describing the cars stored in safehouse garages. This block can vary in size although in the unmodified game it will always be 0x23C7 bytes because there are 50 garages defined. The 80 saved vehicles (4 each in 20 garages) is a fixed number and probably cannot be exceeded. Also, the arrangement of the Garage Car structures in the save is non-intuitive: they follow the pattern Garage 1/Car 1, Garage 2/Car 1, ... Garage 20/Car 1, Garage 1/Car 2, Garage 2/Car 2 ...

Block 10: Zones

This block contains information about map zones in three arrays. The first array is for size and location information for the zones as initially defined in the data file info.zon. The second array contains entries for each of the uniquely-named zones defined in the first array and stores information about things like gang densities and popcycle.dat group info for each zone. Much of this info is set by specific opcodes such as 076C, 076A, 0767, and 0874.) The ID number for a given entry in the first array refers to an entry in the second array. The third array is another size/location array similar to the first but based on the data file map.zon.

One interesting note about this block is that a small amount of corruption here causes the "Taxi Glitch" situation where the taxi mission always tells you there are no fares nearby no matter where you are. The problem is that the first entry of the first array (the SAN_AND zone describing the entire map) gets mangled and the taxi mission references that zone to pick a passenger. For more on this glitch and how to fix it, see the GTAForums thread on it.

Notes:

  1. The ZonePop byte at offset 0x0F appears to use the upper 3 bits for flags. Bit 0x20 will be set if gangs are present in the zone and cleared if no gangs are present. Bit 0x40 is unobserved, and cleared if set manually. Bit 0x80 is set with opcode 09B7 and disables the footcops in that zone.
  2. Map Fog Array: Each byte denotes the state of the certain map sector (00 = not visited / 01 = visited); byte order = N to S (10 rows), then E to W (10 cols).

Police Trigger Types

  • 1 - On Foot with 1 star spawns 2 cop cars moving slowly
  • 2 - In Vehicle with 2 stars spawns 1 cop car moving quickly
  • 3 - In Vehicle with 2 stars spawns 1 cop car at medium speed
  • 4 - On Foot with 1 star spawns 1 cop pedestrian
  • 5 - On Foot with 1 star spawns 2 cop pedestrians
  • 6 - In Vehicle with 2 stars spawns 2 cop cars moving quickly before hitting breaks
  • 7 - In Vehicle with 2 stars spawns 2 cop cars moving quickly
  • 8 - On Foot with 1 star spawns 2 cop cars at medium speed

Notes:

  1. Police Triggers are a special zone consisting of a rectangle defined by 2 ends of the rectangle diagonal, and two rays defined by a starting point and point along the ray indicating the initial direction of travel.
  2. When the player is in the police trigger rectangle and meets the requirements of the police trigger type, then a cop will spawn at the endpoint of ray A headed in the direction of the 2nd defined point.
  3. If the police trigger type includes 2 police, then a cop will also spawn along ray B.
  4. The police are not bound to continue in the specified direction after their initial spawn.
  5. In order to trigger In Vehicle trigger types the vehicle must be moving.
  6. Police trigger zones are activated only once per 40 seconds (the first field is used to control this).
  7. Police trigger zones can be created using opcode 04F8

  • This structure stores information about how a ped of given pedtype (each entry in PedRelationship[32] is separate pedtype, starting from 0 (PLAYER1) to 31 (MISSION8)) behaves toward any ped of other type. Five dwords in this structure (only four of them are used) are the bitmasks, where a bit sets a flag of acquaintance type (respect, like, dislike, hate) to the pedtype of given index (=number of bit). Say, if the 4th bit (counting from zero) in PedRelationship[5].respect is set, it means that a ped of type CIVFEMALE (pedtype=5) respects a ped of type CIVMALE (pedtype=4).
  • These structures are filled with data from the file ped.dat. The relationship flags could be changed using opcode 0746 and similar.

Notes: The order of the flags corresponds to the order the IPLs appear in gta3.img. These flags only affect non-stream IPLs; stream IPLs are always enabled regardless of flag value. (*plus something on the opcodes used to enable/disable the flags*)

Block 24: Unique Stunt Jumps

OFFSET  TYPE        DESCRIPTION
0x0000  dword       Number of Unique Stunt Jumps (USJ)
0x0004  StuntJump[] Jump structures -- each is 0x44 bytes in size; see details below

StuntJump -- See note below
  0x00  float[3]    Start zone point 1 (x,y,z)
  0x0C  float[3]    Start zone point 2 (x,y,z)
  0x18  float[3]    Land zone point 1 (x,y,z)

  0x41  byte        Boolean: is USJ found
  0x42  byte[2]     (Align)

The starting and landing zones are cubes; each is defined by 2 points -- point 1 is the lower, left, front of the cube and point 2 is the upper, right, rear. These cubes are aligned with the coordinate axes and not rotated at all. If a vehicle enters the starting zone while airborne, the USJ triggers (and is marked as 'found'); if the vehicle then lands inside the landing zone, the USJ is successful (and is marked as 'done') and the reward is given.

Block 25: ENEX Connections

  0    dword           count
  4    word[count]     source index of enex path
----
  Structure:
  0    word            source index (break loop if value = -1)
  2    word            flags
  4    word            destination index
----

Enex Path: Normally 0 for outdoor saves, or 1 with the source index of the enex used to access the interior where the game was saved. The enex path may be longer on modified saves. Additional links are appended to the path. The enex path is used to display the zone name for the destination before CJ arrives in the zone.

15 8000 32768 delete enex           Enex is deleted when used

New enex connections can be added to the save after the save is created if temporary (burglary) connections are not present (indoor or isolated saves). The flags and links for existing connections will not be updated by changes in the IPL file. If the enex structure is removed from the block (except for the -1 terminator) the game will remap all connections based on the current IPL configuration.

Block 26: Radio Data

This block contains data relating to various radio stations. The bulk of the block is an array of data structures for each station. Not much is known about these structures currently but part of the data seems to be a record of which tracks have played recently. Following this array of structures there is a collection of byte flags which are related to high-number player Stats. These Stats are used to trigger different episodes and radio clips throughout the game. Note that the "set by" comments refer to missions in the original, unmodified game and they can obviously be set at different times instead. 

0x0000 StationInfo[14] State info for radio stations; each is 0x110 in size -- see details below
0x0EE0 byte            Cities Unlocked (stat 181)

0x0EF7 byte            month day when the stats above were updated
0x0EF8 byte            hour when the stats above were updated
0x0EF9 byte            hours to the next stats update (commonly 24 or 168)
0x0EFA byte            updating flag (1,2,3)

0x1C end

Padding

Following the last data block is a variable amount of padding. Since every save file is exactly 0x31800 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. Because GTASA internally uses a buffer of 0xC800 bytes for writing a save, each byte of padding data is simply a repetition of the data located 0xC800 bytes before it. While it is not strictly necessary to follow this convention for the padding when writing a modified save file, it is consistent with the original game and makes modifications harder to detect.

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 0x317FC 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.

Tools

Available tools for editing of the save file content:

Allows editing of any save data directly in the hex editor. Also contains the script to recalculate the checksum.
