Fur Fighters Dreamcast compression format info

Now this is what I need help for. Some compressed and noncompressed samples.


0compressed samples.7z

Some basic info so far.

12 byte header


Pak
50 61 6B 1B

compression bytes little endian
electric.spr(or any 32x32 spr)

in pak header
0C 08

little endian
08 0c

file size in bytes
2060

Last four bytes can have some value, or just 0x00. Don't know yet what it could be for.


Seems to be some form of lz compression.

Somewhat close, but not quite.
lz11
lz4


Dreamcast demos use 548, COMP_BIZARRE (From Quickbms defs.h) for compression of .sq images in bitmaps.
