Doom wads like most roms and stuff are illegal to freely distribute (unless of course it's shareware doom) so the best thing to do would be to buy a real copy of the game or do a search for Doom shareware in google.
lol, thanks, i got the wad and I got doom to run. OMG it runs at perfect speed and perfect graphics with no lag downs, thanks again. Oh, on the official doom site they dont have a demo of DOOM2, anyone know where I could get it?
