Kosinski compression
From Sega Retro
Kosinski compression is the name given by the Sonic Community to a format used in Sonic games for the Sega Genesis/Megadrive. It is named after the person who cracked it, Brett Kosinski. It appears to be an extension/variation of the LZSS algorithm.
Kosinski compression is used to compress the following data types:
- Sonic the Hedgehog - 256x256 block mappings.
- Sonic the Hedgehog 2 - level graphics, block mappings and level layouts.
