I have figured out a bit about the descent .pig file. 

Here goes: (in decimal, not hex) 

    0000: (long) Number of bitmap entries 
    0004: (long) Number of sound entries (?) 
    0008: Start of first bitmap entry. 
        Each bitmap entry has the following format (still working on it) 
            0000: (8 character string) name 
            0008: (char) ??? 
            0010: (char) width??  usually 64 
            0011: (char) height?? usually 64 
            0012 -> 0015: Who knows? 
            0016: (char) NULL 

            In short, each bitmap directory entry is 17 bytes long. 
            Each sound directory entry is 20 bytes long. 

This is a very preliminary hack and I'm sure its only 3% correct. Has anyone 
else tried their hand at hacking descent?
