I always thought of Moon Patrol as being a Horizontal scrolling game, but when I looked at it in MameWah tonight I noticed it was described as "Vertical Raster". Hmmmm... so I started it up and it played in, basically, a square.... "wierd", I thought to myself, but it didn't look squeezed.
Cranking it up in Mame32 it's stretched horizontally to fit my PC monitor and it looks more like I remember it... but the text does appear to be stretched out horizontally a bit.
From the Moon Patrol cab pictures I've found, it does seem that it was on a horizontal screen, but the "Screen Resolution" (according to MAME) is 240x248 which is almost square.
Were there vertical cabs of this game? Why would the dimensions be so square-y? Anyone?
