I like how they do the effect too, it’s three 13 in displays, with the center one being real and front mounted and the side ones being reflected from below like non-deluxe lightgun game cabs
enjoy this video shamelessly stolen from the Output thread:

you also can’t accurately recreate the aspect ratio of this setup on modern widescreen displays because it’s straight 4:1 (3 4:3 displays) whereas 2 16:9 screens would be ~3.55:1 and an ultrawide is just ~2.33:1
more on topic, X-Men is also kinda hard to drive because it’s at a comfier ~2.66:1 but it would be more at home on an ultrawide
also I have no idea if Mame accurately replicates how the 6-player version runs (the hardware for all versions are the same and they achieve driving two displays by having each one only refresh at 30hz)
