The problem is that the way to know the final time, is by having the total time displayed in the HUD and then looking in the top right corner to see what the final time was, right before the episode is completed. Other game ports, like PrBoom+, show the same screen as you see after finishing a level also after finishing the final level, before showing the episode story ending.
I did notice the option "Show ENDOOM screen", but I believe that refers to the story ending, which is not what I am looking for.
Would this be feasible?
