Crispy Doom

Crispy Doom is a limit-raising medium-resolution Doom source port based on Chocolate Doom. Its name means that 640x400 looks "crisp" and is also a slight reference to its origin

Crispy Doom is a fork of Chocolate Doom that provides a higher display resolution, raises the static limits of the Doom engine and offers further optional visual, technical and gameplay-affecting enhancements while remaining entirely config file, savegame, netplay and demo compatibile with the original.
