I don't know if anyone remembers the arcade at the amusement center I mentioned recently, but I went back last night and stumbled upon a sit down Space Harrier unit I somehow missed last time.
Well, I tried it out and sure enough, up = down and vicey versey. I guess Mame uses the opposite control to better suit keyboard/gamepad play.
It was still hard to control, since you reach the edge of the field of movement very quickly. Like you only get to move around the center half of the screen or something.
Shortly after trying it, I couldn't find my girlfriend. When I finally tracked her down she was playing the full sized hydraulic(?) Galaxy Force II, spinning all around. "It was awesome" she says.

I forgot to bring my video camera, but hope to video all the classic arcades next weekend(new ones I noticed include Kunio Dodgeball, Frogger and Centipede).
