GAME.DTZ (DaTa Zlib) is a file regarding PS2 and PSP versions of GTA LCS and GTA VCS. It contains data files, as well as main textures and models analogue to existing 3D era games compiled in binary form. It is compressed using the zlib/deflate algorithm [1] (max compression). Its contents can be viewed using any zlib compression/decompression utility, such as offzip [2] and zdrop, though some can be viewed with DTZ Editor [3], a tool made by Dageron. All info provided is about decompressed version
Header
The Header for both GTA LCS and GTA VCS versions is defined like so:
0x0 [4b] "GTAG" signature 0x4 [4b] 1, unknown 0x8 [4b] size of decompressed file 0xC [4b] ? 0x10 [4b] offset to global table of offsets 0x14 [4b] number of offsets in global table 0x18 [4b] same as 0xC 0x1C [2b] ? 0x1E [2b] ?

Data Formats
IPL
IPL Info
The header of GAME.DTZ points to 5 IPL info tables: Buildings, Treadables, Dummys, EntryInfoNode and PtrNode. The first 3 are 16 bytes in size and are defined like so:
4b int Offset to IPL data 4b int ? 4b int Number of IPL lines 4b int ? 16 char Name of IPL info (Buildings, Treadables, etc...)
Need more info on EntryInfoNode and PtrNode
IPL Structure
The IPL data is structured like so:
4b float m00 4b float m10 4b float m20 4b float Unk1 4b float m01 4b float m11 4b float m21 4b float Unk2 4b float m02 4b float m12 4b float m22 4b float Unk3 4b float Position-X 4b float Position-Y 4b float Position-Z 4b float Unk4 24b ? 2b int Corresponding Model ID 6b ?
The IPL is basically a matrix:
[m00, m01, m02, Position-X] [m10, m11, m12, Position-Y] [m20, m21, m22, Position-Z] [unk1, unk2, unk3, unk4 ]
The bottom row is Leeds Engine stuff, not useful for generating IPL. They only matter in memory. Someone may provide more info
Generating IPL in text format
In order to calculate the original rotation values, this algorythm comes in handy:
if (tr > 0) {
float S = sqrt(tr+1.0) * 2; // S=4*qw
qw = 0.25 * S;
qx = (m21 - m12) / S;
qy = (m02 - m20) / S;
qz = (m10 - m01) / S;
} else if ((m00 > m11)&(m00 > m22)) {
float S = sqrt(1.0 + m00 - m11 - m22) * 2; // S=4*qx
qw = (m21 - m12) / S;
qx = 0.25 * S;
qy = (m01 + m10) / S;
qz = (m02 + m20) / S;
} else if (m11 > m22) {
float S = sqrt(1.0 + m11 - m00 - m22) * 2; // S=4*qy
qw = (m02 - m20) / S;
qx = (m01 + m10) / S;
qy = 0.25 * S;
qz = (m12 + m21) / S;
} else {
float S = sqrt(1.0 + m22 - m00 - m11) * 2; // S=4*qz
qw = (m10 - m01) / S;
qx = (m02 + m20) / S;
qy = (m12 + m21) / S;
qz = 0.25 * S;
}
And finally, since 3DS Max that originally created IPL negates X,Y,Z:
Rotation X = -qx Rotation Y = -qy Rotation Z = -qz Rotation W = qw
IDE
On both LCS and VCS, 0x3C points to a table containing offsets to IDE lines and 0x38 specifies the number of values in the table. Each value-offset is assigned an ID, starting from 0. If it so happens and the value-offset is 0x00000000, then the ID isn't assigned to any object. The structure is like so:
LCS
8b - 4b int Name of the object (CRC32 Hash encryption) 4b - 1b int Type (1: objs, 3:tobj, 4:weap, 5:hier, 6:cars, 7:ped) 1b int Count 2dfx (ex. if 2dfxID=8 and Count2dfx=4, then the assigned IDs are 8, 9, 10, 11) 2b int Collision in .DTZ (boolean, 0:not in DTZ, 1:in DTZ) 4b int offset to collision (.col2) 2b int 2dfx ID 2b int Object.DAT ID 2b - 2b int Texture ID 4b int Type (CRC32 Hash encryprion) 4b int offset to model (if no .mdl exists in .DTZ, then it's 0)
Type 1 OBJS:
4b float Draw Distance 1 4b float Draw Distance 2 4b float Draw Distance 3 (if object is LOD, then disappearing distance) 1b int Mesh Count 1b int ? 2b int Flags 4b int if object is LOD, offset to IDE ID of original object, otherwise =0
Type 3 TOBJ:
4b float Draw Distance 1 4b float Draw Distance 2 4b float Draw Distance 3 (if object is LOD, then disappearing distance) 1b int Mesh Count 1b int ? 2b int Flags 4b int if object is LOD, offset to IDE ID of original object, otherwise =0 4b int Time On 4b int Time Off
VCS
8b - 4b int Name of the object (CRC32 Hash encryption) 4b - 1b int Type (1: objs, 3:tobj, 4:weap, 5:hier, 6:cars, 7:ped) 1b int Count 2dfx (ex. if 2dfxID=8 and Count2dfx=4, then the assigned IDs are 8, 9, 10, 11) 2b int Collision in .DTZ (boolean, 0:not in DTZ, 1:in DTZ) 4b int offset to collision (.col2) 2b int 2dfx ID 2b int Object.DAT ID 2b - 2b int Texture ID 2b ? 2b - 4b int Type (CRC32 Hash encryprion) 4b int offset to model (if no .mdl exists in .DTZ, then it's 0) 4b float Draw Distance 1 4b float Draw Distance 2 4b float Draw Distance 3 (if object is LOD, then disappearing distance) 1b int Mesh Count 1b int ? 2b int Flags 4b int if object is LOD, offset to IDE ID of original object, otherwise =0
Type 3 TOBJ:
4b float Draw Distance 1 4b float Draw Distance 2 4b float Draw Distance 3 (if object is LOD, then disappearing distance) 1b int Mesh Count 1b int ? 2b int Flags 4b int if object is LOD, offset to IDE ID of original object, otherwise =0 4b int Time On 4b int Time Off
More info soon
2DFX
2DFX data is read directly from DTZ header. Each line is 64 bytes (depending on the 2DFX type, padding is used at the end). 24 bytes are common for all types (only 0, 1 and 3 are used). Each line is assigned an ID, counting from 0.
4b float Position X (relative to centre of the object) 4b float Position Y (relative to centre of the object) 4b float Position Z (relative to centre of the object) 4b - 1b int Colour R 1b int Colour G 1b int Colour B 1b int Unknown (usually 200.0, like in Vice City) 4b int Type
Type 0 Lights:
4b float View Distance 4b float Outer Range 4b float Size 4b float Inner Range 1b int Flash 1b int Wet 1b int Flare 1b int Shadow Intensity 4b int Flags 4b int Offset to corona texture 4b int Offset to shadow texture 8b -
Type 1 Particles:
4b int Particle Type 4b float Strength X 4b float Strength Y 4b float Strength Z 4b float Scale 20b -
Type 3 Peds:
4b float Rotation X 4b float Rotation Y 4b float Rotation Z 4b float Rotation X (again) 4b float Rotation Y (again) 4b float Rotation Z (again) 4b int Behaviour 12b -
The format is the same as the plain text version of III and VC. More info can be found on: 2DFX
OBJECT.DAT
It's read directly from DTZ header. Each line is given an ID counting from 0.
