Notes and Comments
- Some files and the directory are compressed using zlib
- Filetype Identifiers:
- 0 - Uncompressed file
- 1 - Compressed file
- 256 - Directory
- Initial value for the CRC32 Checksums is 0
- The encryption algorithm is a modified TEA version (it has the same characteristic bitshifts)
- There exists multiple versions of the same algorithm but with different 128-bit keys and different deltas
- The Encryption Identifier will tell you which algorithm to use
- The hashfunction for the filenames is crc32()
- The Timestamp is the Windows FILETIME struct
Encryption Table
The data of some files may be compressed or encrypted. The Encryption Table maps the Filetype Identifier to an algorithm that can handle the data. The table has 8 available slots. The Filetype Identifier 0 is mapped to slot 0, Filetype Identifier 1 is mapped to slot 1 and so on...
If a slot is null, the data is neither compressed nor encrypted. Otherwise the slot contains an Encryption Identifier that tells you how to handle the data.
Example: We have a file with File Type Identifier 1. We look at slot 1 of the encryption table and will find the value: 0x9BB3F065. This tells us that we have a file that is compressed and that the first 16 Bytes of the filedata are encrypted with a simple XOR-algorithm.

shrlvid0.bba contains 22 .bik file (some audio, mostly video). There is one corrupt file (don't know for sure why since the entire archive is unpacked and all other files work).

shrlsnd0.bba contains 3 mp3s performed by the Viking character Thordal in game as his special power. So far i've been able to extract 64 mp3's with success from this archive, but after that, I keep getting 1 good frame, and then rubbish, and this pattern keeps repeating. I have also found some unencrypted/uncompressed PCM Wave headers (RIFF & fmt tags), so I'll try to put that in the mix to get a better picture of the archive composition. The linked script above extracts the 3 mp3s from Throdal.
