It's already been a while but Eruanna has released the latest version of the ZDoom fork port QZDoom which is mostly notable because it adds latest features to the engine since the development of ZDoom itself has been stopped by randi heit. One of the most common features of the mod is true-color rendering in software which also goes to dynamic lights and all the crazy stuff, only GZDoom was capable with its hardware renderer - until now. Get the classic vibe.
