Nick Baker wants you to be certain of one thing - he isn't the same Nick Baker as NiGHTMARE. Also known as Robot Junkyard (Workshop, I guess), he published his debut nine-map episode / Doom Pack for Doom II in early 2014. While it is theoretically compatible with vanilla, RJW only tested it in ZDoom, and that's what I played it in, so I can't speak as to the existence of any of the typical ZDoom follies. His notes suggest using a limit-removing port at the least, but if you want all the bells and whistles you'll need something capable of processing MAPINFO lumps, or else you'll miss out on the rearranged skies and music files.
