I'm trying to find out how to tell if certain mapsets use BOOM or UDMF or w/e other format they might be using. Is there a sure way I can identify different maps and what map format they use?

check them in slade. all 3 main formats have different lump structure. UDMF is obvious as a text file. I think all hexen has a behavior lump or something while doom lacks it. advanced map features are a giveaway in game of course.

Thank you for your reply that helps a lot actually.
