A GTA Text (GXT) file contains almost all texts that are displayed on the screen of GTA2 and above. The location of those files may differ between the various game versions, but they are usualy located in a text\ folder inside the games installation directory. Except for GTA 2 There is one GXT file for each language, but the number of gxt files does not define the number of supported languages by the game.

File format

GTA 2

GTA 2 begins with a header followed by a TKEY block followed by a TDAT block. Within the TKEY block is an array of TKEY entries containing the offset to and the name of the TDAT entry. A TDAT entry contains the text to be displayed in the game.

Header
Offset Type Description
0x00 char[4]
  • "GBLE" - English
  • "GBLF" - French
  • "GBLG" - German
  • "GBLI" - Italian
  • "GBLS" - Spanish
  • "GBLJ" - Japanese
0x04 word File version, always 100
Block 1 (TKEY)
0x06 char[4] "TKEY"
0x0A dword Size of TKEY block
0x0E TKEY[n] Array of TKEY entries, where n is the number of entries. All entries are sorted in alphabetical order.
TKEY (0xC bytes):
Offset Type Description
0x00 dword TDAT entry offset. The value is relative to the location of the first entry of the array, which is, in absolute term, size of TKEY block + 22.
0x04 char[8] TDAT entry name

The absolute location of the TDAT block is the size of TKEY block + 14.

Block 2 (TDAT)
Offset Type Description
0x00 char[4] "TDAT"
0x04 dword Size of TDAT block
0x08 TDAT[n] Array of TDAT entries, where n is the number of entries. Entries are not sorted in alphabetical order but their order comes from the order of their entry in the GXT source file.
TDAT (m * 2 bytes):
Offset Type Description
0x00 wchar_t[m] An array of wide characters (2 bytes per character) to be displayed in the game, where m is the number of characters. The array is terminated by a null character (0x0000). The location of the entry in absolute term is TDAT entry offset + size of TKEY block + 22.

Characters beginning with 0x21 denote gang dialogue:

  • 0x216B: Krishna
  • 0x216C: Loony
  • 0x216D: Russian
  • 0x216E: Neutral
  • 0x2172: Redneck
  • 0x2173: Scientist
  • 0x2179: Yakuza
  • 0x217A: Zaibatsu

GTA III

GTA III is nearly identical to GTA 2 but without the header. It begins with a TKEY block followed by a TDAT block. Within the TKEY block is an array of TKEY entries containing the offset to and the name of the TDAT entry. A TDAT entry contains the text to be displayed in the game. The Xbox version of Vice City uses this format also.

Block 1 (TKEY)
Offset Type Description
0x00 char[4] "TKEY"
0x04 dword Size of TKEY block
0x08 TKEY[n] Array of TKEY entries, where n is the number of entries. All entries are sorted in alphabetical order.
TKEY (0xC bytes):
Offset Type Description
0x00 dword TDAT entry offset. The value is relative to the location of the first entry of the array, which is, in absolute term, size of TKEY block + 16.
0x04 char[8] TDAT entry name

The absolute location of the TDAT block is the size of TKEY block + 8.

Block 2 (TDAT)
Offset Type Description
0x00 char[4] "TDAT"
0x04 dword Size of TDAT block
0x08 TDAT[n] Array of TDAT entries, where n is the number of entries. Entries are not sorted in alphabetical order but their order comes from the order of their entry in the GXT source file.
TDAT (m * 2 bytes):
Offset Type Description
0x00 wchar_t[m] An array of wide characters (2 bytes per character) to be displayed in the game, where m is the number of characters. The array is terminated by a null character (0x0000). The characters are based on the character table in the fonts.txd file, which mostly follows ASCII. The location of the entry in absolute term is TDAT entry offset + size of TKEY block + 16.

Vice City, Liberty City Stories, and Vice City Stories

Vice City, Liberty City Stories, and Vice City Stories begin with a TABL block, which was first introduced in Vice City, followed by an array of TKEY blocks. Within each TKEY block is an array of TKEY entries containing the offset to and the name of the TDAT entry. A TDAT entry contains the text to be displayed in the game. The Xbox version of Vice City uses GTA III's format instead.

Block 1 (TABL)
Offset Type Description
0x00 char[4] "TABL"
0x04 dword Size of TABL block
0x08 TABL[n] Array of TABL entries, where n is the number of entries. All entries are sorted in alphabetical order except the first one, MAIN.
TABL (0xC bytes):
Offset Type Description
0x00 char[8] TKEY entry name
0x04 dword TKEY entry offset. The value is absolute.

The absolute location of the TKEY block is simply the TKEY entry offset. The TKEY block format is slightly different for the first block named MAIN. Hover over the dotted lines for information specific to that block. All other blocks follow the format shown below.

Block 2 (TKEY)
Offset Type Description
0x00 char[8] TKEY entry name
0x08 char[4] "TKEY"
0x0C dword Size of TKEY block
0x10 TKEY[n] Array of TKEY entries, where n is the number of entries. All entries are sorted in alphabetical order.
TKEY (0xC bytes):
Offset Type Description
0x00 dword TDAT entry offset. The value is relative to the location of the first entry of the array, which is, in absolute term, TKEY entry offset + size of TKEY block + 16.
0x04 char[8] TDAT entry name

The absolute location of the TDAT block is the TKEY entry offset + size of TKEY block + 16.

Block 3 (TDAT)
Offset Type Description
0x00 char[4] "TDAT"
0x04 dword Size of TDAT block
0x08 TDAT[n] Array of TDAT entries, where n is the number of entries. Entries are not sorted in alphabetical order but their order comes from the order of their entry in the GXT source file.
TDAT (m bytes):
Offset Type Description
0x00 wchar_t[m] An array of wide characters (2 bytes per character) to be displayed in the game, where m is the number of characters. The array is terminated by a null character (0x0000). The characters are based on the character table in the fonts.txd file, which mostly follows ASCII. The location of the entry in absolute term is TDAT entry offset + size of TKEY block + 16.

GTA San Andreas / GTA IV Format

Each GXT file contains certain tables with entries. And each entry has a unique CRC identifier and a normal text.

Header

The header contains information about the GXT version.

INT32   - 4b   - Version (0x080004 for ASCII, 0x100004 for UTF-16)

Table Block

The Table Block contains data about the subtables and their offsets.

CHAR[4] - 4b   - TABL
INT32   - 4b   - Blocksize

//Array of [Blocksize / 12 Entries]
CHAR[8] - 8b   - Subtablename
INT32   - 4b   - Offset

The Offset of the subtable points to an 8-byte Char Array with the subtable's name, followed by TKEY. For the MAIN Table this points directly to TKEY!

GTA San Andreas has a limit of max 200 tables to be stored per GXT file.

TKEY and TDAT

TKEY

The TKEY Block of an subtable contains the CRC32-values of the entrytitles. The game calculates the CRC32-value out of a given string and checks if they exist in the GXT.

CHAR[4] - 4b   - TKEY
INT32   - 4b   - Blocksize

//Array of [Blocksize / 8]
INT32   - 4b   - Entryoffset
INT32   - 4b   - CRC32 (Entryname)

The TKEY block is directly followed by the TDAT Block which contains the contents of the entries. The Entryoffset is relative to the TDAT + 8 offset.

TDAT
CHAR[4] - 4b   - TDAT
INT32   - 4b   - Blocksize

From here the entryoffset of each entry points to the content. The content can have different sizes. However it always ends in '\0'! For Example "Hello!" needs to be transformed to "Hello!\0" here and this gives a size of 6 bytes (To tell it in a short form content is a null-terminated string). If this is the 1st content in TDAT the next got an offset of 0x06!

Encodings
GTA SA          : Windows-1252 always.
GTA IV(8 bits)  : Custom Encoding
GTA IV(16 bits) : Well, its a fake 16 bits encoding, all you need to take care about first 8 bits(1 byte). 
                  Eg. A3F4 C2DD E922, read only A3, C2, E9.


Sorting

The sorting method for TABL, TKEY, TDAT is as follow:

Section Sorting method
TABL Sorted in alphabetical order
TKEY GTA SA: Sorted from the lowest crc32 to the highest crc32,

GTA IV: Unknown. Perhaps randomized order.

TDAT Not sorted. The data is stored from the first line to the last line in the GXT source file

GTA 1 Format

GTA 1 language files have .fxt extension, and it's different from other games' format. Except the first 8 byte it uses very simple encryption. To get text, just substract 1 from every byte. First 8 bytes have different encryption, probably just to confuse modders. For every byte substract a value returned from left shifting 99.

Character maps

These character maps display all possible characters that can be used in the GXT file. Each character is represented by a hexadecimal value, which can be constructed by reading the value in the leftmost column and then the value in the topmost row, e.g. a capital letter A is represented by 0x41 in hex.
