There is a flag in PSXDoom which causes a sprite to become inverted, transparent, and multiply the HP by 2.
I discovered this several months ago after hacking the PSXDoom rom I ripped myself and took a look at the MAP05 things list and searched around for the flag for the Nightmare Spectre thing at the very beginning of the level.
The AC hex number (or decimal, 172) was the flag for that THING.
So I changed the flag to something like EC and the Nightmare Spectre became a regular Spectre. I was able to try the flag on other sprites which resulted in Imps, Shotgun Guys, and Medikits to become inverted and transparent and a shy bit tougher (exclude the Medikit). You could actually just open up a sprite in an image program and invert the sprite and perhaps lower the brightness and raise the contrast.
I believe the actual Nightmare thing flag is 160.
Some others tidbits:
The common transparent thing flag is appears to be 224.
The transparent thing flag 32, is like 224, but appears brighter, MAP25 and MAP34 are a couple of levels that use this on Spectres.
The transparent flag for walls is 1024.
Oh, one other thing I found out was that PSXDoom still had the Nightmare Mode intact, though, how to play that skill I am unsure of, but how I found it was I modified DEMO1.LMP's skill level and changed it to one number higher, which resulted the game demo playing on high caffeine so to speak.
