This might sound like a frankly rather dumb question, but can Ultimate Doom Builder be used to make WADs that can be 100% compatible with Vanilla DOS (or DOSBox) Doom? I might have received the motivation to create my own mapset, but I would love for it to be vanilla friendly friendly and compatible. I'm only asking because I read on the Official Doom Wiki that Ultimate Doom Builder is primarily aimed towards ZDoom and GZDoom, so I just want some clarification as to whether or not it can be used for Vanilla DOS Doom or any other non-ZDoom source port.

Hi, I'm trying to play the final idgames release of the megawad and I keep getting the same 'R_InitTextures: 32 errors' error message on both PrBoom+ and DSDA-Doom. Is there a way I can fix this so I can finally play the megawad?

I would rewrite history to prevent Karl Marx from ever being born.

Anything made by TimeofDeath! ESP3 in particular!

Anything that is NOT GZDoom.

GZDoom

There may have been people asking about this in the past, but I really would love to know how can I play Master Levels for Doom II as a merged single WAD using a non-ZDoom based source port like Crispy Doom, PrBoom+, or DSDA Doom. I can't seem to find useful information anywhere, not even on the Doom Wiki. Any help would be greatly appreciated!
