You can't change the monitor orientation without changing the game orientation as well: Aerofighters 2 has horizontal monitor (being for Neo!) but vertical scrolling. If you put the monitor on its side you'll have vertical monitor but horizontal scrolling...
I suspect that what bconner has seen is Aerofighters 1 which wasn't a Neo game, had vertical monitor and vertical scrolling (a la Raiden).
