Doom1 Support Techincally Works, but you must choose the correct episode when loading doom.wad as your IWAD, or else it won't work. :P
All four episodes of Doom1 are linked as a full 36 map escapade [thanks to Kyle873 for referring me to the MAPINFO stuff he used for DoomRPG :P]
Made a script that emulates the special scripts used in E1M8, E2M8, E3M8, E4M6, E4M8 and MAP07 for killing certain monsters [or families of monsters in this case] so the randomly spawned/evolved monsters count towards activating these scripts. :P
