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

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

GTA San Andreas / GTA IV Format

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!

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	Sorted from the lowest crc32 to the highest crc32
TDAT	Not sorted. The data is stored from the first line to the last line in the GXT source file

GTA III / GTA Vice City Format

GTA Vice City GXT is almost like San Andreas GXT, but differs in

There's no header
In TKEY, the keys are stored in a char[8] array instead of a crc32 hash

GTA III GXT is like GTA Vice City GXT, but there's no table, the GXT starts immediately at TKEY block.

Table Block (Vice City only)

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!

TKEY and TDAT

TKEY

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

//Array of [Blocksize / 12]
INT32   - 4b   - Entryoffset
CHAR[8] - 8b   - Entryname

Unlike San Andreas entrynames are stored directly in 8b chararrays here. This means to calculate the entries in the table you have to divide the blocksize through 12. The Entryoffsets are relative to the end of the "TDAT Header". This means you have to add the entryoffset to the stream position after the TDAT size. (TDAT_Offset + 8 + Entryoffset), to get to the entry.

TDAT

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

The TDAT-Block contains the strings which are displayed by the game. But here are some differences towards San Andreas. The strings are encoded in unicode, which means that each character takes the space of 2 characters (which means 2 bytes per character). Mostly the last byte is 0x00.

Sorting

The sorting method is like the San Andreas method, just changing the TKEY sorting method.

Section	Sorting method
TABL	Sorted in alphabetical order
TKEY	Sorted in alphabetical order
TDAT	Not sorted. The data is stored from the first line to the last line in the GXT source file

GTA2 Format

Except for additional header at beginning GTA2 GXT files are identical to GTA3 format.

The first 4 bytes can be one of following, and identify the language for the file: GBLE - english GBLF - french GBLG - german GBLI - italian GBLS - spanish GBLJ - japanese

A uint16 file version follows which is always 100 (decimal)

Text is stored with some specialities, characters are 16 bit while only one of these bytes is actual character the other may store special data such as gang message icon id, etc.. the text is zero-terminated.

The rest of file is same as gta3 with familiar tkey & tdat sections.

Keypresses

You can use opcode 00E1 to check if these keys are being pressed.

Unused

Here are some keypress codes only used during development stage. They were removed or replaced later but probably they are still working. Maybe this is useful for further research. Some are only used in PS2 Version.


~TAKE_SCREEN_SHOT~
