Test Drive Unlimited Xbox 360 bnk files...

[Darius6]

Hello. I'm looking in how to extract these bnk files from the Xbox 360 version of Test Drive Unlimited.

These bnk files contain the following:

3DG (this is the file format for the meshes) and 2db (this is the file format for the textures)

The PC version of this game also has bnk files which can be opened in software like 3dsimed however for the Xbox 360 version of the game they cannot be opened.

The main reason as to why they won't open is due to the files from the Xbox 360 version are in big endian whereas the ones in the PC version are in little endian...

Is it possible to convert big endian to little endian?  And if not is it possible to extract the files individually from these bnk files?

I've posted  samples below:

The _I in these bnk files represent the interior of the said vehicle.

Rims are stored separately in a folder.

For more context these are the DLC 6 vehicles which was the last DLC for the game and were never ported to the PC version of the game.

Speaking of files? Then usually the answer is "no", because you would need the offset of every byte , DWORD, float and string in the source file to treat them accordingly.

(If the file were a block of floats, for example, it would be possible.)

 

Getting something useful out of bnk will require some fidling, I guess:

Harder than expected without a decent magic table of counts (if any):
