The SWBF1 munger applies a transformation to the rotation of bones that SWBFII doesn't. (Or something.) I spent a good couple hours trying to work it but math isn't my strong point and I was just burning myself out on it. I may take another crack at it after a break.
Also the z-coordinate of the position is flipped for the SWBF1 bones, but that was easy to figure out.
