The Unity port version of nerve.wad does have a widescreen intermission screen. If you want to make that file I linked use Doom 2's intermission for NRFTL as a stopgap, duplicate the file interpic.lmp with the name nvinter.lmp.
Woah, I never knew about the intermission screen of NERVE in the Unity Port... And yeah, that's what I immediately did after you sent me the pk3, but regardless, thanks for helping me out and hopefully other people if they stumble upon this thread.
