Introduction

Darkhorse is an LZSS-based algorithm, using an LZMA-like mode of the SitxRangeCoder. The algorithm has been reverse-engineered, but not written up yet. For now, there is only source code available:

(The window size seems to be stored as a single byte at the start of the stream. The window size is 1<<byte, except when the result of this is less than 0x100000 (through either a small value, or overflow), in which case the window size is 0x100000).
