New WAD Tool

New WAD Tool (NWT) is a DOS WAD editor for Doom, Doom 2, and Heretic, created by D. Berndmeier of The Innocent Crew in 1996. Much like DeuTex, it can be used to add, edit, and replace lumps inside a WAD file. NWT also has the capability to edit TEXTURE and PNAMES lumps, view graphics and listen to sound resources, and clean WAD files (much like Cleanwad).
