Help with Doom .wad files

acctually if im correct, it will also recocnise plutonia.WAD and tnt.WAD, which are packaged with doom collecters edition cd, along with doom2 and ultimate doom.
I might be talking bout the latest version of doom for psp, but give it a try.

is there anyway to get doom for mac os x?

well, theres this one version of doom that is, well, interesting. Its only for Unix and i think Mac OS X.
