A GXT file contains almost all text that are displayed on the screen of GTA3 and above. The files are located in the text folder. An entire list of all entries is available with Sanny Builder.
Contents
File Stub
Each GXT-File can contain certain tables with subtables and entries.
San Andreas Format
Header
The header contains data about the tables and their subtables.
INT32 - 4b - Version? (Allways 0x080004) CHAR[4] - 4b - TABL
Table Block
The Table Block contains data about the subtables and their offsets.
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 (Entrytitle)
The TKEY block is directly followed by the TDAT Block which contains the contents of the entries. The Entryoffset is relative to the TDAT + 4 offset.
TDAT
CHAR[4] - 4b - TDAT INT32 - 4b - Blocksize
From here the Entryoffset of each entry points to the content. The content can have diffrent size. However it is allways endet by '\0'! For Example "Hello!" needs to be "Hello!\0" here and this gives a size of 6 bytes. If this is the 1st content in TDAT the next got an offset of 0x06!
Special Characters
Here is a list of special characters for german language sets and their UINT8 Values:
| Character | Value |
|---|---|
| Ä | 131 |
| ä | 154 |
| Ö | 145 |
| ö | 168 |
| Ü | 149 |
| ü | 172 |
| ß | 150 |
CRC32 Calculation
Here is a sample source which converts an CHAR[]-Array to an CRC32-polynom:
private static ulong[] table = new ulong[] {

public static ulong StringToCRC32(char[] Value)
{
ulong CRC = 0xFFFFFFFF; // Register Base-Value
for (int i = 0; i < Value.Length; i++)
{
CRC = ((CRC & 0xFFFFFF00) / 0x100) & 0xFFFFFF ^ table[(ulong)Value[i] ^ CRC & 0xFF];
}
return CRC;
}
(C#/C migration by Aschratt)
It is impossible to get a string out of an CRC32-value. The game only checks if 2 values are identical. However this is not a very reliably way cause there can be more than 2 CRC32 Values for one string. But the probability for this is not very high!
