In fact there is a way of getting a DOS version of the Doom Collector's edition. I happen to have this version and it is not that crappy. All you need to do is download doom 1.9 shareware from , then copy your original .wad file from the collector's cdrom, then download doom 1.9 patch again from . Then run the patch and you will have doom and doom2, and final doom dos versions which you will patch each in its separate directory. The only thing missing is final doom setup.exe (which shows final doom in the setup menu title) but you can still live without it.
