Searching around, I found that you're not the first to have this question. All of the LEGO action games of late have had a .fib file in them, and no one seems to know how to break into it. Judging by its size, I'd be willing to bet it's a resource archive of some sort.
Looking at the data in a hex editor, I see what appears to be an identifier "FUSE" and a version number "1.00", and in the data there seems to be many instances of the bytes 4E 01 00 40, followed by three bytes, then 8B 46. At least one field looks like an offset or size indicator pertinent to the archive itself (if that's what it is).
This is probably something better suited for ROM Hacking, although the implications certainly suggest all sorts of interesting tidbits not normally visible in the game. If you can scrounge together some other .fib files from other LEGO games, it might help to figure out what kind of data they're representing and how that data is stored.
For the record, I'm not volunteering my services, but I'd be happy to share some ideas in regards to how to proceed with breaking into this thing.  |
