The latest retail patch is v3.0. Digital distribution versions are already fully patched.
BStone is a native port of the engine source code with support for higher resolutions and other features. Linux users should download the hosted precompiled version if you do not wish to compile the software from source code and extract bstone bin file into the main game's folder.
Use bstone with the --no_screens command line argument.
To run Blake Stone correctly in DOSBox change cycles=auto to cycles=max. Leave all other DOSBox settings at their defaults.
WDC supports editing maps, enemies, music and many other game features. You must start a new game for the map changes to take effect.
