So I got a Russian game called New Robinson and it has all the assets packed into these DAN/DAT files.
Here's what I got on them so far:
0x00 - header magic (NL)
0x04 - number of files
0x06 - number of files again
0x0E - seems to always be 0xBAAB
0x10 - uncompressed size
0x14 - compressed size
0x20 - for each file: 0x20 bytes of unknown data
After that there are actual files with start offsets aligned to 0x04 bytes. Files are usually compressed but some DAN files are uncompressed in which case uncompressed size is same as compressed size.
What I want find out is what this data at 0x20 is and the compression used.
