Hi everyone!
It always annoyed me that Vice City Stories seems neglected. The "mystery" file "GAME.DTZ" has all the game info.  Anyway, I thought I could share what I've found. If anyone has some info about this, please share! Let's smash those "?"! 
I'm also gradually adding all the info discovered on gtamodding.com!
Download of the extracted resources is planned to be available, check spoilers.
Special thanks to Ash_735, cj2000, Gladion and The Hero

Thank you very much! Do you also happen to know about the data before it? it has a float 0.0001 21 times!

[The Hero]

No. I haven't looked at this file until today. At 0xAC there is the offset to weather types list (0x185690) with 256 2 byte entries.

[guard3]

Thanks again, though I'd assume they are 254 (4 bytes at the end are blank, like placeholders). If you know anything else, anyone, feel free to post.

Haven't figured out the four unknown values yet, but they all are used for drawing the colour filter (which is the reason I'm reversing this in the first place)
EDIT: updated. radiosity limit is the value above which a color is considered a highlight. radiosity intensity is a multiplier after half the limit has been subtracted from the frame buffer. blur alpha (internally multiplied by 0.8) is the strength of the blur effect, blur offset is the pixel offset (the current frame is blended three times for the blur effect, at offset,0; 0,offset, offset,offset)

That's helpful for converting it to pc format. I plan to upload the extracted files for convenience, so thanks again

VCS has 90 different particle entries. The values are very similar to Vice City's ones. However, the CR seems to be to the second power, compared to Vice City (ex VC:20.0 -> VCS 400.0) I have no idea what the last 8 bytes are.

[The Hero]

Since you say the header has unknowns I took the liberty of documenting that thing: http://www.gtamoddin...locatable_chunk
I also "documented" the general MDL format: http://www.gtamodding.com/wiki/MDL

[guard3]

Nice one! I talked with cj2000 and I have some explanation about the header, though I really haven't checked those myself, so I haven't updated those...

That relocatable chunk really is a big thing

Spoiler

He has also made a pdf with stuff about mdl. I don't know if you've taken a look at it, but it could be useful

[The Hero]

I've seen it. Not too useful although I noticed he had the different modelinfo types that I only recently figured out. Well whatever.

[The Hero]

For reference here the structure of an android LCS game.dtz. I know the game doesn't use it but the code that would load it is still there. All the values are simply copied to the variable on the right (except the timecycle data is memcpy'ed to a statically allocated region). I have made no effort comparing this to the PS2 games yet, but they don't seem to match 100%. (EDIT: judging by http://gtamodding.ru/wiki/DTZit looks like the PS2 version is only missing the unused value at 0xB4).

Well, it has no dtz, but it *could* load one. See LoadResourceImage

Grand Theft Auto Vice City Stories PEDSTATS.DAT Documentation by guard3-cj2000
0x4CC250 is a table (B0, or 176 bytes). It's composed of 42 4-byte values, 
each representing an offset that corresponds to a line of PEDSTATS.DAT
Each line is 34 (52 bytes) in size and is defined like so:

-	ID			LE	integer		4 bytes
B	Flee Distance		LE	float		4 bytes
C	Heading Change Rate	LE	float		4 bytes
H	Attack Strength	        LE	float		4 bytes
I	Defend Weekness	        LE	float		4 bytes
J	Flags			-	integer		1 byte
-	-			-	integer		1 byte
D	Fear			-	integer		1 byte
E	Temper		        -	integer		1 byte
F	Lawfulness		-	integer		1 byte
G	Sexiness		-	integer		1 byte
A	Name			BE	character	26 bytes

Here you can download pedstats.dat! .docx (documentation), .xlsx (values), and a .dat file. Because pedstats are hardcoded, in order to use that .dat without modification, simply set 0x53027F (memory offset) or 0x12FE7F (exe offset via hex editor) to 0x2A. Thank you Gladion!

Not that important, but:

GTA VCS Car Color Data

R integer 1byte
G integer 1byte
B integer 1byte

That simple. Though VCS has 230 colors for cars (more that any 3d era game!)

 

 

VCS Cull.IPL   
  2b: Box Lower X Coord
  2b: Box Upper X Coord
  2b: Box Lower Y Coord
  2b: Box Upper Y Coord
  2b: Box Lower Z Coord
  2b: Box Upper Z Coord
  2b: Flag 1
  2b: Flag 2

That one I acquired from gtamodding.ru.

But I converted it, so grab both files here:

CARCOLS.DAT

CULL.IPL

[Ash_735]

Though VCS has 230 colors for cars (more that any 3d era game!)

This is because it's split into two, one batch is used for peds (the colour of pedestrian clothing) and THEN you have the carcols.

[guard3]

I think that ped colours are stored in the IDE section of each ped. No?

GTA VCS 2dfx data Documentation by guard3
GTA VCS has 686 2dfx data lines, each one being given an ID starting from 0, all the way to 685.
The IDE section loads a 2dfx ID, which is then assigned to an object. The structure and format is (almost)
the same as GTA VC. Each line is 64 bytes, 24 of which are common among all 2dfx types, and 40 more, whose structures
differ according to the 2dfx type.

COMMON:
Assuming VC is structured as: A, B, C, D, E, F, G, H, I, then VCS is:
4b float   B Coordinate-X (relative to the centre of the object)
4b float   C Coordinate-Y (relative to the centre of the object)
4b float   D Coordinate-Z (relative to the centre of the object)
4b -
1b integer E Colour-R
1b integer F Colour-G
1b integer G Colour-B
1b integer H Unknown (like in VC)
4b integer I 2dfx Type

Type 0 (Lights):
Assuming VC is structured as: J, K, L, M, N, O, P, Q, R, S, T, then VCS is:
4b float   L View Distance
4b float   M Outer Range
4b float   N Size
4b float   O Inner Range
1b integer Q Flash
1b integer R Wet
1b integer S Flare
1b integer P Shadow Intensity
4b integer T Flags
4b offset  offset to corona texture (J)
4b offset  offset to shadow texture (K)
8b -

Type 1 (Particles):
Assuming VC is structured as: J, K, L, M, N, then VCS is:
4b integer J Particle Type
4b float   K Strength-X
4b float   L Strength-Y
4b float   M Strength-Z
4b float   N Scale
20b -

Type 3 (Peds):
Assuming VC is structured as: J, K, L, M, N, O, P, then VCS is:
4b float   K Rotation-X
4b float   L Rotation-Y
4b float   M Rotation-Z
4b float   N same as K
4b float   O same as L
4b float   P same as M
4b integer J Behaviour

I think that ped colours are stored in the IDE section of each ped. No?

Nope, they're apart of carcols dat, just come first in the order (which was throwing us off when we first used it), for VCS PC we split them up into carcols and pedcols but the source just has all of it in carcols.

[guard3]

Ok then, thanks for the info 

[csillam_faszlama]

Could you get handling.cfg and weapon.dat files extracted?

[Ash_735]

Those two have already been found and documented I think, but would be good to list here too. VCS has quite a few additional values though compared to other GTA's which is where people tend to get thrown off.

[csillam_faszlama]

Additional values for handlings, for weapons, or for both? I hope, that those files are mostly similar to their Vice City variants, so I can convert the lines for San Andreas... Will check, if I find anything about them anywhere else.
