Loading Game Files (animation files) into 3ds max or any other 3D software

i got a source release in public together with all its assets
from models to animation to texture everything in it
the models (skin and bones) DirectX file (.x file) can be loaded in 3ds max via script or any 3d software.

my problem is the animation files, which is stored inside the .BIN file

the process on making .BIN files is
by making animatio n 3ds max or any 3d software
export to .X file ( with animation)

then that .x file is loaded to the game tool,

then the tool
extracted the animation frames scale, position and rotation of every bone
and turn it into game readable .BIN file ( where the animation is contain)

problem is,
we have the .BIN of the game since its already given in the client files

I want to convert that .BIN file into any format readable in any 3D Software like 3Ds max
any format as long as I can load the resulting file to 3D software and export it to fbx

it could be a new application to convert the BIN file to be loadable to 3D softare

or anything u can do
as long as it can be loaded into 3d software with all the animaton data intact
And we acan convert it to fbx

Again the full source code is available to be examine if you want
its all in the engine
i also prepare
the files for you to test

here the link since the uplaod files in only limite to 25 MB

thank you
