cocktail games not fliping?

[keltech]

hi
i'm building a cocktail cab and at the stage to test the pc out

i'm using arcadeos 2.52 and dmame
i've set the games in arcadeos to -L so i can see them verticaly.

the problem i seem to have is when i select a game like galaga for instance and change the dip switch setting to cabinet = cocktail
the game doesn't flip automatically when player 1 uses their life?

am i doing something wrong?

any advise would be much appreciated!!!

did you reset or restart the game after making the switch?  this is necessary for any dip switch settings to take effect.
