Been interested at modding this game ever since I discovered the JAM unpacker file in this site. Now i'm wondering if anyone could make a tool to extract the .WKA file which from what I learned are the animation file for the game.

Before we don't have a skeleton nothing will happen.

There is a file called .akc which is i think where the model's skeleton are stored if that is what you're talking about.

It's in a plain text so idk if there's a way to turn it into an armature in Blender

Should be possible - but not from a screenshot.

Here's the akc file. Let me know if you found a way convert it to an armature

akc sample.7z

Thanks! Will take some time. (Reminds me of my forgotten or unwritten ASCII parser code snippets.)

Orientation values are a quat, afaics, but what is this matrix? Hopefully it can be applied without a hassle.

Nice. Could you make a script to automatically convert akc to smd?

I don't write scripts, usually. It's a tool. But it's not user friendly.

This smd example should do to tackle *.WKA files.

If you want to work with WKA file first then here. Hopefully someone else made a script so other WKA file could be tested on

wka sample.7z

I hope so, too. But sadly the WKA format is not clear to me. Don't see a relation to the skeleton's bones.

All we have is curves:

You still looking into it?

Guess it needs to be debugged and I don't have the time for that. Plus I can't see any reference to the bones in the wka file.
