Ever wanted to play all the official Doom releases as one WAD without having to exit and launch your favorite sourceport again? Now it's finally possible, thanks to the efforts of JPL. His tool WadSmoosh combines all the data from every available official Doom release into one huge file and even combines the Final Doom Evilution Map31 fix or does not include the Master Levels and No Rest for the Living, if Doom 2 isn't present at all. So get your copy, collect your IWADs and merge them together for full lazyness and 9 episodes of Doomin'.
