I'm looking for a conversion of the Tokyo Extreme Zero map (2001 PS2 version). There was a project started on the Zenhax forum, but it wasn't finished. I want to extract a specific sector. Thanks for any information.

old topic 

https://www.zenhax.com/viewtopic.php@t=3291.html

I don't see 'map' mentioned in that topic, it's only about 'models'?

Okay, admittedly he doesn't mention the map. But the goal is to know how to retrieve the mesh with the textures. He must proceed in the same way for the map, surely. At least I assume so. Thanks.

The bms script tofuman mentioned in his last post should be this one from Aluigi:

# Tokyo Xtreme Racer Zero
# script for QuickBMS http://quickbms.aluigi.org

open FDSE "CDDATA.LOC"
open FDSE "CDDATA.000.DAT" 1

get FILES long
for i = 0 < FILES
    get OFFSET long
    get SIZE long
    get BLOCKS long
    math OFFSET *= 0x800
    math BLOCKS *= 0x800
    log "" OFFSET SIZE 1
next i

Hi sir, I'm a complete noob. I've only used HxD once. Decompressing it with QuickBMS is fine, I know how to do that. But modifying the hexadecimal files, I'd need a tutorial with pictures; that would make it much clearer. And what tool will I need to convert them to mesh afterwards? Again, my apologies and thank you.

Hi sir. Great!  How many files did the script extract from CDDATA.000.DAT?

I have no idea about the extracted files. You'll have to upload some of them. To choose which ones a directory snapshot would come in handy.

Try command

dir *.* /AD > TokyoERZ_directories.txt

executed in command line after extraction. (You'll need to switch to the folder of extracted files for such).

If there are no (sub) directories this command will log the names of the extracted files into TokyoERZ_dir.txt:

dir *.* /s > TokyoERZ_files.txt

Okay, I'll look at all of that tonight. And I'll post screenshots of the folders.

Ok, thanks.

.tm2 should be a texture file. If there's "TIM2" in the .nfc files they should contain textures, too.

If you uploaded one of the smaller .dat files (approx. 500 kB) I could have a look at.

Edited January 8Jan 8 by shak-otay

ok this is a small dat.files

000000000000000b.rar

16 bytes blocks, but this is probably not a mesh:

Sorry for replying only now. Okay, the .dat file doesn't include the geometry. So I'm sending you the 3 other different versions of Difier: 0iv/nfc/sdb. Thank you.

The .sdb file contains 2 TIM2 textures, seems. The other two files contain a bunch of small meshes - no time to assemble them, atm:

Okay, no problem. When you have time, why not? But I think it would be helpful if you could explain it to me when you have time so I can convert it myself. Thank you very much for your efforts.

https://github.com/igorciz777/GUTArchiveTools

igorciz777 created a tool which is able to unpack the toc / dat pair which contains all the files of these games made by genki.

i cant see a single hint about any filenames whatsoever, every file will be named 000xxxxx.ext.

the files get extracted in order, starting with font files, cars, rims, tracks, ui elements, localization
so if you compare it with wangan midnight ps3 (which provides filenames in the toc) it would be possible to somewhat guess the structure for these games,
or at least take notes and move/sort them manually

igrociz777's tool is also able to unpack .dat (or .nfc / sdb - extension seems guessed) files using -cd as a extra command

you'll see instructions how to use it on github -> gut_archive.exe -command "input.dat" "outputpath"
---

the missing filenames are making these games extremely tedious - but at some point, you'll reach standalone .xmdl / .tm2 files for ps2 games and .gim / .gmo for psp games.

the first two games, txr0 and wangan midnight do have .xmdl files, but stacked, sometimes there are two or three structures embeded in one file (lods?),
so you might need to find a filesplitter to cut these on every 0IVX (try asking ai for a python script).

following ps2 games also do have xmdl files, but kept them seperate, no splitting needed.

.tm2 seems to be a common playstation texture container - there are tools and noesis scripts out there to convert these
.gim is the psp texture file, there are noesis scripts aswell
.gmo is the psp mesh file, however the existing scripts crash on these right now, it would require further research on these

---

the vertex blocks are split into <50 vertices chunks - leaving you with a trillion tiny unnamed pieces

but, vertex position is fine, one uv, vertexcolor and dummy positions are supported, not sure about another chunk, might be normals? or a second uv? cant tell

the meshes themself do not show any signs for a face index (playstation 2 typical?) so these get auto generated

sadly kaidou racer 2 and txrd2 did some more changes to the format, still no index buffer 
for some reason - noesis generates the faces wrong right now - maybe someone is able to fix that one

 

ive included both, 010 templates with coloring - helps identifying chunks - and two noesis scripts

make sure to only load one of the two python scripts into noesis, otherwise it will confuse itself and freeze

v1 works for 
02 Tokyo Xtreme Racer Zero
02 Wangan Midnight
03 Tokyo Xtreme Racer 3
04 Kaidou Battle 2 Chain Reaction
04 Kaidou Racer
05 Racing Battle C1 Grand Prix
06 Kaidou Battle
06 Kaidou Battle Nikko Haruna Rokko Hakone
06 Tokyo Xtreme Racer Drift

 

v2 works semi good on
07 Kaidou Racer 2
07 Tokyo Xtreme Racer Drift 2

Hi Guki, this is very interesting. The experts will know what to do, but I don't at all. Thank you for contributing. Genki's games are very rich in maps, roads, and cars. It's a shame that the Sony PS2 or the 3D engine created by Genki is so complex to analyze for those familiar with it. Furthermore, only one has been released on PC in 2025. (It's a DC/PS2/Xbox 360 exclusive.)

well, give it a try at least - unpacking isnt that hard and the noesis script i've sent you will provide you the map you want 🤷‍♂️

Did you get a car? (don't expect to be dragged along)

I checked for the 0000000000000090.nfc file from above. I renamed it to dat and used igrociz777's tool ("1" is an empty folder):

gut_archive -cd 0000000000000090.nfc.dat 1
All files extracted successfully

Then I used Guki's ..v1.py script:

Yes, I know a little about the Noesis tool, so I'm going to do some tests.
