The game's archives are easy enough to extract, but unfortunately it looks like a lot of the files that are probably graphics use some kind of LZO compression that I can't wrap my head around.
Below is a Python script to extract the .tbv files if anyone wants to take a shot or stumbles upon this in the future.
