asteroids/asteroids deluxe on a cocktail MAME machine

[NOP]

Both asteroids and asteroids deluxe originally came in cocktail cabinets, but it I can't seem to find a way to enable cocktail mode in MAME.  (and I'm not talking about the split screen cocktail video option in MAME).  I seem to recall there's a service menu dipswitch, which is sometimes used to set up cocktail modes, but I'm not having any luck. MAME's game inputs only have setups for player 1. 

Is it possible to get asteroids in MAME to flip screens and use 2 sets of controls?  Oddly enough about the only google search I've been able to dredge up on the subject is from me asking about it here back in 2007- which I didn't even recall doing.  heh.  I didn't get an answer then, so maybe someone knows now.

The controls are easy -- do the following in the Input (this Game) menu for each button in turn:
- Press Enter
- Press Esc (changes to "none")
- Press Enter
- Press P1 button (changes to P1 button)
- Press Enter
- Press P2 button (changes to P1 button or P2 button)

The video doesn't appear to be working on my setup either -- IIRC I'm using .LAY/art files from Mr. Do's.

In "Cocktail" video mode, it is upside-down on the top half of the screen with no flipping/repositioning during a 2P game.

In "Cocktail Art" video mode, it is upright in the middle of a rendered wood-grain cocktail table with no flipping/repositioning during a 2P game.

EDIT: Paige found the answer.

Asteroids boards know if they are in a cocktail or upright cabinet because of a pin that is grounded on the cocktail harness but not on the upright.

Unfortunately this does not seem to be in Mame.

I'm not at home so I can't check, but is there a dip switch setting to fix this?

The only dip switches are service mode, language, lives, center mech, right mech, and coinage.

Joymonkey linked to a related Mameworld post.  The link is broken, Mameworld search doesn't turn up anything that old, and the Internet Wayback Machine is no help, either.

Looks like Asteroids etc. will finally be getting a real 'fake' cocktail mode!

I just live with Asteroids being upside down for P2. It's not like there is a 'right side up' in space
