Chocolate Doom is a portable branch of the classic doom.exe experience from the days of DOS. The author, Simon Howard, has worked to ensure Chocolate Doom, which is nothing more than a directly modified version of the released iD Software source code, has zero changes that affect gameplay, look, or feel, and also re-created a DOS-like setup program to configure the game much like the original setup.exe. The project also maintains versions of the engine for Heretic, Hexen, and Strife. Chocolate Doom provides: chocolate-doom - the Doom executable chocolate-doom-setup - the Doom setup executable chocolate-heretic - the Heretic executable chocolate-heretic-setup - the Heretic setup executable chocolate-hexen - the Hexen executable chocolate-hexen-setup - the Hexen setup executable chocolate-strife - the Strife executable chocolate-strife-setup - the Strife setup executable chocolate-server - server for up to 4-player net games Due to the port re-implementing the original games as closely as possible, all original game PWADs and demos work flawlessly. Other original features include a PC-speaker driver, just like the DOS PC-speaker driver, and a working -left and -right network command parameter system for the 'surround display' setup that was obtainable with the original DOS executables over an IPX network.
