I tried to implement this slice-by-8 CRC but couldn't do it the way I wanted - without bloated zlib tables and stuff. Maybe because I don't get what updcrc(), getcrc(), setcrc() are and what they actually do. The whole program is magical, there is no way to find do_de/compress(), nor anything like that, so it was difficult to actually find relevant code. But anyway, for a start I manged to make `makecrcs8.c' to generate CRCs lookup table (attached). Regards wrotycz
