NFS No Limits ".OBB"

Post by AMG »

The big ".OBB" archive containing the game data was easily openable until the latest update
Here's a link for the archive:

It's a format that requires some time.
Considering that most of its files are just PNG images, I highly suggest you to opt for a file ripper.

Very chaotic format.
The DATA section has a complex structure so I opted for a work-around.
No filenames.
All the SBIN files are automatically splitted in their sections.

Thanks alot, as always!
Just wondering, the previous versions of the archive had more ".M3G" files, with bigger dimensions too (the car models were in that format) but now I only see few of them, and with a very low size aswell.

Do you mean something caused by the script?
As far as I know it has been able to extract most of the files from the archives, but the work-around used in the DATA section doesn't allow to extract really everything and there are some false positives.

No, not caused by the script, but as you said probabily some still unpacked data
I notice there are some ".DAT" packages which are the biggest ones after unpacking

The DAT files with the random data in them (open them with a hex editor) are probably just false positives.
So check their content first and then delete them if they contain garbage.

After checking, I found out these .dat files are actually .m3g 3D data, in fact i've used the M3G2FBX tool by Chipicao and it worked just fine even with .dat extension because I guess no matter the extension the format remains.

An update about the FMOBB-02 format, I have seen some formats using the compression 2 that I don't know what it is.
The compressed data starts with the bytes "16 00 00 00".

The folders with strange names are textures, the textures are stored in BARG files and can be extracted with Dragon Unpacker or Jaeder Naub tool, and for 3D models are stored in Unknown compression folder, .DAT files, sadly there's no way to open this files

PD: the compression 16 00 00 00 is a type of mesh compression, this requires some of deep investigation
