Summary
MAP20: Gotcha! as viewed in FastDoom 0.4 using DOSBOX 0.74-3, using the 386 binary and with the -potato, -flatsurfaces, -flatsky and -flatshadow parameters in low resolution mode (80x200 fullscreen)

Screenshot taken using Snipping Tool in a window, primarily because -devparm does not work in 0.4.
