Is there any way to simulate Tag 666 on maps other than MAP07 or MAP32 on Doom 2?
I created a megawad (for personal use) that combines the Master Levels into an additional episode (thanks to the new MAPINFO support), but I'm having problems with the map Mephisto's Mausoleum, which is supposed to take place of MAP07. The problem is I haven't named this level MAP07 because I don't want it to override the vanilla map, so i'm looking for a way to simulate the behavior of Tag 666 for this map (or other PWADs I might load).
I tried turning on the compatibility flag "All bosses trigger 666" to no avail. Apparently it doesn't work for Mancubuses.
Any help will be appreciated, thanks.
