Here's the solution to that pesky 7-4 maze in Vs. Super Mario Bros. (recorded on Switch, works on a real arcade machine, too)
Maze section 1:
-Bottom
-Top (Use mid to get on top. It's ok to drop to the bottom as I show in the video, after making it through once.)
-Top to exit (use mid to get on top again)
Maze section 2 (after the fire bar):
-Mid (on the first two platforms)
-Top (on the second two platforms)
-Top (jump to the third two platforms)
-Bottom to exit
Don't mind the audio. I put it on Bass Boost in the settings in order to get that old-school feel.
