This is a library for compressing and decompressing files in Sega's "Kosinski" format (an LZSS variant). The goal is to produce a compressor that outputs data identical to Sega's own compressor. Moduled Kosinski is also supported.

Included are basic frontends for a compressor, a decompressor, and a comparison utility.

Sega's compressor had a fair few bugs, causing it to produce files with sub-optimal compression ratios. Lucky, none of these issues harm the integrity of the compressed data. See lib/kosinski_compress.c for more info.
