Temple Run models

I would port over the models from Temple Run mysel, but they’re in a custom format with extension .bksb. I was wondering if anyone here knows how to write an importer for 3DS Max. Then, I would be able to do the rest.

Additionally, if anyone actually CAN write an importer for .bksb files, then an exporter to the same format would be awesome as well. That way, we could put in our own custom characters, coins, environment, etc.
