PS4 DRIVECLUB - dat

[lolwatt]

Hey,

Another PS4 game. This one has several .dat files in numerical order.
I uploaded a bunch of them (06, 08, 09) and a few unrelated files, in case there is some information there - I dont really know. lol
If more files are needed, let me know.

It's a bad format, too long to explain all the bad things in it
The only thing I can do is posting the script for decompressing the DAT archives, decompressing does NOT mean extracting so this script is totally useless, I post it mainly for myself:
*script removed, check my next posts*

So I tried the script to see if I can extract some content manually after the decompression, and it seems that the script throw an error when trying to decompress some heavy files (like game000.dat [ 1gb size]), tried quickbms in normal and 4gb version, and still, they both give me this error :



( I have 64 GB Ram and 758 GB free space on the HDD )

With other smaller files (like game004.dat [315Mb size]) it works fine.



(CF: created a new account on zenhax since I can't recover the old one)

ok, I have updated the script to dump the decompressed file directly to disk instead of memory.

I have removed the old script and have uploaded it on my website with an integrated "EVOSLITL" search&dump, basically searches all the occurrences of the "EVOSLITL" magic and dumps the data between them... basically the only thing that can be done with this format:

Ah nice !

So I tried the updated script (before being removed) and it work now on all files ( all the .dat are decompressed ).

About the EVOSLITL search and extract, I think it's a good idea, because it seems some files are even put in plain simple format (like maya etc...) by looking at the hearders.

So finally succeeded to output some 3D from Driveclub.

I took the game034_unpack.dat (I use the complete decompress .dat)

Then, vertices indices starting at 0x132DE, prior to that, at 0x132D8, 0C = 12 (will be the strip for the vertices).

The faces indices start at 0x3D35DD (I think).

This is pretty nice! I wish I could learn to reverse stuff, but I always get stuck.
Is the format simple? What about the textures?

[zaykho]

The format seems not that complicated, but I lack of automatic tools to help me putting everything together ( multiple vertices group with different vertex/uv block linked to one full faces indices list).

As for texture I think I did find them too (didn't tried to export them yet)

[zaykho]

Starting to get faces working too:

hi people please help me I proceeded to the instruction given in relation to quickbms I send you an image I it is not how to do I only need texture for a project I'm not the processors that must be followed if you could help me thank you all

All I get (with driveclub.bms) from the main .dat (extracted with PS4PKGViewer.exe from .pkg) is other .dats mostly, that are "incomplete" to extract. What to do next? I need Intro videos (1.00/1.28), any help, where to look?

[NRave]

Great feedback, thank you very much...
