Crispy Doom

Crispy Doom is a limit-removing enhanced-resolution Doom source port based on Chocolate Doom.

Its name means that its internal 640x400 resolution looks "crisp" and is also a slight reference to its origin.

Crispy Doom is a friendly fork of Chocolate Doom that provides a higher display resolution, removes the static limits of the Doom engine and offers further optional visual, tactical and physical enhancements while remaining entirely config file, savegame, netplay and demo compatible with the original.
