Do the special PlayStation/Saturn/N64 Doom maps exist for the PC?
I’ve talked with creators and designers at id, Williams, and Midway, and the answers I’d received were that the maps are the property of Williams/Midway, and they were never made available anywhere to the public as PC-compatible WAD files, nor are there plans to ever publish them as such. However, some talented Doom enthusiasts have created their own versions of these maps and, in general, they are faithful reproductions. Source ports, such as ZDoom, are required in order to use some of these. You can find links to the console Doom maps, and to various source ports, on the Doom links page.
