Modding discussion for Driver 2: The Wheelman is Back.

Hi!

I'm Chris; I'm looking at Driver 2's LEV files; this is my first post; and I want to discuss what I've discovered so far.

For my investigation I'm using Driver 2 PAL Europe. I'm analyzing DRIVER2\MLEVELS\CHICAGO.LEV (i.e., the multiplayer Chicago level) because 1) multiplayer levels are smaller and simpler than single-player levels, and therefore easier to analyze; and 2) Chicago is the level I have most memories on. But if not stated otherwise, whatever I say is also valid for the other cities and levels (I'm running some unit tests here).

To proceed, you need to have worked with a hex editor before. Please also mind the PSX was a little-endian architecture — i.e., the hexadecimal number 90ABCDEF would be found in the LEV file as EFCDAB90. Also, KiB is 1024 bytes and kb is 1000 bits.

Confused enough? ;) Let's begin with the general structure of the file. The layout is mostly chunk-based, i.e. each matter is assigned a unique ID and a size (both being 4-byte-values). If one does not need or understand a chunk of data, it can easily be skipped. Well, there's lots of exceptions (Driver 2 is constantly paging in from the CD-ROM, and requires random access to do so), but for the beginning this is sufficient. Furthermore, this post states that the chunks are internally called lumps, and that's how I will refer to them.

So, let's open Chicago. The first thing we see is:
Code: Select alloffset      value(s)
\/\/\/\/   \/\/\/\/\/\/\/\/\/\/\/\/
00000000   25000000 F8070000
This is the ID (0x25) and size (2040 B counted from the 8th byte; i.e., pointing to 00000800) of the dictionary lump.

It contains eight 4-B values:
Code: Select all               00080000 00B80200         
               00C00200 00A00800
               00600B00 00380100
               00980C00 00E00D00
Each pair describes one of the major lumps in a file. The first pair describes the 2nd lump starting at 00000800 (Recognize that number?) and being 174 KiB large; and so on. This is the same for any LEV file you open. What's also the same is, the first lump listed here will be of type 00000023, and the third one will be of type 00000024. (I have not analyzed the second and fourth lump in the list, as their format is slightly different. These lumps keep most of geometry and textures, and I'll come back to them later.) What's after this, on the other hand, differs from level to level – for any kind of CHICAGO.LEV, the remaining space is padded with magic numbers; for the other LEV's, it holds offsets I have not yet further looked into.

Let's proceed with the 00000023 lump, as there is some interesting information in it:
Code: Select all00000800   23000000               type
            10B30200               size (points to 0002BB18)
Inside are the sub-lumps 0000005, 0…22, 0C, 19, 02, 16, 1C, and FF.
05 keeps texture names:
Code: Select all               00000005               type
               C81B0000               size (points to 000023C8) — consider: the chunk data ends at 000023C8, but the next chunk will start at 000023>D<8 because chunks are always 4-B-aligned!
                  <zero-terminated strings>      904 (0x388) of them; each one is a texture name
These are easy to spot even with a text editor; don't bother processing them — they're referenced by the next lump (22):
Code: Select all000023D8   22000000
            A8200000               size (points to 00004488)
               46000000               number of active texture atlases
               89030000               equals the number of texture names in the previous chunk
               Texture atlases incoming! Consider: There were 0x46 atlases declared, but 0x47 actually occur! I guess the last one is skipped …

Those are really interesting. Consider Driver 2 gathers several small textures in a large texture, called an atlas. The 70 texture atlases declared here will feed more than 800 actual textures.
The offsets are really interesting: The offsets are mostly 20–30 KiB apart. If you go through the file with a hex editor and take notes where you find texture-like looking blocks, those blocks are also mostly 20–30 KiB apart. But unfortunately, the offsets given in the file do not point to valid locations — some of them even point beyond the file. I guess there is additional information coded in the 11 least significand bits (as texture atlases seem always aligned to 0x800), and I'll need to take a closer look at this later. But first, proceed with the rest of the 22 lump – actual textures:

There is one entry for each texture atlas. Wait, no — there are even too many entries. But fortunately, the last entries look a little different than the others (sometimes width and height is just zero), and so I'm confident they can just be skipped. So: read only the first 70 entries, skip the rest.

For each texture atlas, a collection of textures referencing this atlas is given. A 4-B integer gives the number of textures on the atlas, and then the entries follow immediately. Each entry is in the form of
Code: Select all2-B integer with unknown meaning
2-B integer with offset of the texture name in the previous lump
two 1-B integers giving the origin of the texture on the atlas, in pixels
two 1-B integers giving the dimensions of the texture on the atlas, in pixels, where 0 means 256.
E.g. you know the first texture atlas is referenced by 30 textures, and their names are:
  • CTA (the string at 0x00000810 + 0x0000), which is a 64×24 texture starting at (0, 0);
  • CARSHAD (the string at 0x00000810 + 0x0004), which is a 32×64 texture starting at (64, 0);
  • … and so on.
(How do I know it's origin and dimension? Well, the PSX supports only 256² textures, and in many cases, origin + dimension equals 256, but never more. I also verified one entry manually in MSPaint ;) )

Okay; this was quite a lot. I'm working on the next post while you're reading (the posts here have a character limit); if there are any questions, please feel free to ask :)

So, let's have a look at the lump hierarchy again:
Code: Select all00000025
00000023
+ 00000005
+ 00000022
+ 0000000C
+ 00000019
+ 00000002
+ 00000016
+ 0000001C
+ 000000FF
00000024
+ 0000001E
+ 00000001
+ 0000001A
+ 00000028
+ 00000029
+ 0000002B
+ 00000014
+ 00000018
+ 00000021
+ 00000015
+ 000000FF
The last post was about 25, 23, 05, and 22. Proceed to 0000000C:

This one looks like 00000005, but this time, empty strings (i.e., strings consisting of no more than a zero) occur:
Code: Select alloffset      value(s)
00004488   0C000000               type
            72060000               size (points to 00004B02) — unaligned again!
            <zero-terminated strings>      356 (0x164) of them in Chicago; many being empty
These are very likely model names. I have not yet found the place where they're referenced, but the number 0x164 should be remembered as it will come back later.

Now for 00000019. To be honest: I have no idea what's the purpose of this lump. It starts with a 4-B integer, and if this integer is FFFFFFFF, then 16 2-B values follow. In any case there are also three 4-B integers:
Code: Select all00004B04   19000000
            D83C0000               size (points to 000087E4); 535 (0x217) entries (of which ca. 220 start with FFFFFFFF)
               DB000000                                                               00000000 0D000000 01000000
               FFFFFFFF 2184 428C 4290 4294 6398 839C 839C 84A0 2184 6390 A4A0 C5A4 E6A8 0000 0080 0080 01000000 0D000000 01000000
               FFFFFFFF 2184 638C 8490 A594 C694 E798 E798 089D 2184 8490 08A1 29A5 4AA9 0000 0080 0080 02000000 0D000000 01000000

               …
               C7000000                                                              01000000 1B000000 3F000000
               C8000000                                                              02000000 1B000000 3F000000
               C9000000                                                              03000000 1B000000 3F000000
               CA000000                                                              04000000 1B000000 3F000000
               CB000000 FFFFFFFF
I tried to associate them with the model names, but neither their number nor any value proved a relation. These values do not resemble any geometry I've found so far neither. It is noticable that FFFFFFFF most often occur in blocks of five, although there are exceptions. Ideas are welcome.

The next lump is 00000002. It can be grouped into 202 8-B entries:
Code: Select all000087E4   00000002
            00000650               size (points to 00008E3C); 202 (0xCA) entries

               0002 0000 0042 E021
               00FE DEFF 001F 0029
               …
Notice FFDE in the last line. This is one of the most common numbers, often used for models. This implies 00000002 could define an array of vertices. Actually, interpreted as X, Y, and Z, it looks like this:
Image
These points might define the shape of cars, of a skyline, or of a Chicago map (we'll see one of those later). Who knows.

Even more mysterious are 00000016 blocks. There are many of them, and in contrast to the rest of the data, they entries are rather 'fat' with 142 B each:
Code: Select all00008E3C   00000016
            92090000               size (points to 000097D6); not aligned!

13 more of those follow; I won't be repeating them here. I have not yet decoded their data, but visualizing them in 3d space leads to bizarre Bézier-like curves. I'd guess it's motion capture data.

We're almost at the end of the first quarter of the file! Just two more lumps:

0000001C must be skipped entirely for now. I had a hard time finding regular patterns in it, and I think the entries are 24-B each.

Eventually, 000000FF marks the end of the super lump. Its size is always zero, and it returns control to 00000023, which has then reached its end.

In the next lump (00000024), we'll see where this neat Chicago map comes from:

But I need to get some sleep first ;)

Reflections CHUNK File Format...V1. These are CHUNK files, no doubt in my mind. These are so easy to read, I can write a BMS script to split this into individual files :P

Yep, these definitely are CHUNK'd files. The dictionary up top with offsets and sizes, and then of course the sub-chunks that have lengths inside as well.

LUMP files, the grandaddy of CHUNK files. This is what I find funny...

Lump - A compact mass of a substance, esp. one without a definite or regular shape.; The first part has an ID and size, but serves as a dictionary pointing to other sub-lumps! And those sub-lumps can have a size as well!

Chunk - Divide (something) into chunks.; The dictionary containing ALL of the files are at the very top, with each sub-CHUNK following a specific format to create a special kind of file format.

I have not tried writing modified data back to a CD image, but considering Driver 2 has been modded before (i.e., there is no dedicated protection mechanism), if we find out where exactly the cars are stored, they can be modded, yes.

I've got stuntman lying around somewhere, but I'll take a look later. Driver 2 has priority now.

Well, not the entire file is built up like this (because chunks are too slow for random access, which is required by PSX's low RAM). For example, the actual level is subdivided into tiles, and those are written into the file following a different format (it's actually stuff for an upcoming post). If I remember correctly, only the 1st and 3rd entry in the dictionary is readable as chunks/lumps.

To the others: Thanks for your kind words.

I'll write on then.

Edit: I won't get that post finished today; sorry :(

CHNK files?... like driv3r also uses a CHNK format

i need to get driv3r back on my computer to see if i can do something!

Okay, so the first entry of the dictionary is parsed. Since the 2nd and 4th entries are in a different format, we'll proceed to the 3rd entry, which is quite like the 1st.

Again, this is a chunk-based format. The super lump is now 00000024.

The first sub-lump (00000001) is a list of blobs: The number of blobs is given as a 4-B integer, then for each blob its size (4-B integer) and its data follow:

Surprisingly, the number of blobs equals the number of model names declared in the 0000000C lump of the 00000023 super-lump, so I'm pretty sure this is model data. If you have a closer look at the data above, you may notice the formatting: The lines consisting of four 2-B integers are vertices; the other lines are triangles and quads:
Code: Select all0000 8CFF 7700 0000
            ^^^^ probably texture coordinates
        ^^^^ Z
    ^^^^ Y
^^^^ X

1500 0400 04 00 1A 19 0058 3F58 3F97 0097 00BF 5BFC
        ^^ ^^ ^^ ^^ vertex indices
    ^^^^ number of vertices (0004 for a quad)
Exporting the first blob of multi-player CHICAGO.LEV this way leads to these vertices:

Obviously, the vertices are not yet right. The major problem with the block is finding out how many vertices and polygons there are, and I have not yet worked this out.

Proceeding to 000BF618, where the 0000001A sub-lump is located. I don't have an idea on this one (apart from it being 2-B values), and it is mostly empty, so I'll just skip it.

The next lump is 00000028, which is a 4-B number (the number of entries) followed by 28-B structures. Each structure begins with two signed 4-B integers, which are X and Z positions. I have not yet had a look at the other data, but I'm pretty sure it will contain model indices somewhere, because if we look at the coordinates, it does look a lot like model insertion positions:

The same goes for 00000029, which seems to have the same format, but with less entries:

Now for the last lump I've analyzed: 0000002B. From what I can see, it again has a layout of a 4-B integer as number of entries, and then the given number of entries. Each entry is made up of eight bytes with unknown purpose, and a 4-B integer whose value is either 00000002 or 00000003.

I have not yet looked at the following lumps, whose types are 00000014, 00000018, 00000021, and 00000015.

I'll proceed to the actual tile data the next time. A quick preview:

Okay, just converted the vertices and triangles (without any textures or colors) of the 355 Chicago models. Along with Tanner's head I can identify tires, limbs, traffic lights, and something which might resemble buildings.

The format of a model header is:
Code: Select all4-B unsigned int      size of the model
2× 2 B               ???
2 B                  FFFF if the model has vertices
3× 2 B               ???
2-B unsigned int      number of vertices
2-B unsigned int      number of faces
4-B unsigned int      offset of vertices counted from after the size of the model
4-B unsigned int      offset of the faces
3× 4-B unsigned int   probably offsets of normals and colors

Vertices are given as signed 2-B integers with X, Y, Z, and zero.

Faces are a lot more complex; I'll test other LEV files first. The structure reminds of what I had seen in the Driver Texture Editor source code, but with type IDs being dramatically different and different formats due to the PSX not supporting floating-point numbers.

I can't wait to see the cars! We need to convert Driver 2 cars to Driver! And then we can also recreate them in glorious HD! :D

A great idea, i know it isn't easy but it could be the beginning of a Driver 2 PC version with solved problems of frame rate and others. Only if we could import the cities into Driver 1. Although probably we couldn't use on foot.

I have found various buildings, trains, plants, signs, even highways. But I have not yet found any cars, sorry. Whatever will come, it will take a certain while …
