Chocolate Doom aims to accurately reproduce the original DOS version of Doom and other games based on the Doom engine in a form that can be run on modern computers. Unlike most modern Doom engines, Chocolate Doom is not derived from the Boom source port and does not inherit its features (or bugs).

Chocolate Strife is an accurate and complete recreation of Rogue Entertainment's "Strife: Quest for the Sigil". It was created through more than two years of reverse engineering effort with the blessings of the original programmers of the game.

Chocolate Strife requires game data to play. Commercial game data can be packaged using "game-data-packager".
