WMMT5 model ripping help

[wood5578]

So I'm trying to rip the models from one of Namco's arcade racing game, Wangan Midnight Maximum Tune 5. I have done a bit research into the model files and they all seemed to be using .nud models similar to Pokken's NDWD, although the way of storing multiple objects is a bit different, I'll explain later on.

There are 3 model formats used in this game, which is are .mdl, .bin & .nud. Among all 3 file format, the .nud ones are the only ones that could be properly imported by RTB's Pokken NUD importer. The .mdl and .bin are actually containers, but the importer is unable to import properly. Unlike Pokken, the way it stores multiple objects is slightly different : 

Here are part of the hex-view of two of the different file formats,

MDL car file :


BIN track file (has been renamed to .nud to test importing) :





Importing the MDL files without manual extraction with RTB's Pokken NUD will not import anything but for the BIN files does import the first (top) model located in the file, though the rest remains unimported.

Through manually seperating the NDWD file inside either of the file to its independent NUD, the NUD importer is able to import them, the image below is from a MDL file :

Is there any tool that can unpack two of these format into independent NUDs or a script there could Import all of them? The attachments are samples for the two files which I'm unable to import and a NUD from the same game for reference. Greatly appreciated if anyone could help!
