Screen flips for Player 2 (but I don't want it to!)

Okay, feeling like a complete idiot here. Wanted to try Lunar Rescue (lrescue) in MAME and no matter how I play with the settings, the screen always gets flipped 180 degrees for player two as if in cocktail mode. Hit the Tab button - the Driver Configuration is for an upright cabinet. Go to Video Options - it's set for 4:3. Same thing with Spectar (spectar) and Polaris (polaris), two more games I'm trying for the same time today. What am I missing?

Cocktail mode DIP switch is set to on. Hit tab, go to the DIP switch sub-menu and turn it off. If you can't do it from there you may have to enter the games' own service mode and switch it off (usually F2), or you can use the 'carpet bombing' method; delete the NVRAM folder contents for each game.

But Sune, Carpet Bombing doesn't work on the moon. I tried that previously against those fish from the Darius games and the entire universe ended up smelling like sushi for a week or so.

Thanks for the reply. When I go into Lunar Rescue's dip switch menu, all I see is three settings: "Lives" (as in number of lives per game), "Unused", and "Unused". I tried to access the game's service mode but can't figure out how to do that.

Lunar Rescue required cutting a few traces and adding a jumper to change it to upright.
this also applies to Space Invaders Part II and the SVN and CVN pcb's.
probably applies to other Taito 2 or 3 layer boards as well.
not sure about the boots but maybe similar.
so how can it be added to mame since it's not a switch or setting.
here's a link to show the conversion from cocktail to upright.

Now I'm more confused. Are you saying there's no way in MAME to prevent Lunar Rescue from flipping the screen for player 2? And, if so, is the same true for Polaris and Spectar? Is there a list somewhere of all games that will always (and irrevocably) flip the screen for player 2, thereby rendering them useless for upright MAME cabinets?

The way to switch it for lrescue is to enter the 'Game Configuration' menu item, and the option of Upright or Cocktail is there. However when tested, it made no difference. This is a bug which has now been corrected for the next release.

no i'm not saying it can't be done.
I was playing Tempest earlier and noticed that it had upright or cocktail in the dipswitch settings
but no dipswitch exists for it or at least it doesn't show one, so I guess it could be added the same way.
just figured dipswitch settings were only for dipswitches. 
Edit:
got to stop taking so long to post. 
never even looked in 'Game Configuration'
guess that's where the non dipswitch switches go.

Thanks SO much for the reply! Now I feel a bit less dumb! Is the same true for spectar and polaris?

Polaris always uses players 2 controls even in upright mode, so that's a bug.
Spectar doesn't have a switch for cocktail, when it's player 2 turn the screen flips but he must use player 1 controls, so that also could be a bug.
I'm having a look at Polaris now.
EDIT: polaris is fixed now.
