Yeah these .bbk files are definitely important. Not only do they contain names, offsets, sizes, and dimensions (along with other various info that isn't as useful), but the also house the palettes for indexed images.
The only annoyance is that they're in XML format, which is generally less convenient to handle than binary data. Nevertheless I'm sure I should be able to whip something up.
