I currently use mame 32 on my upright but cant figure out how to make it switch ends when player 2 takes over to use on my cocktail
All you have to do with Mame32 is go into the game hit tab and go into dip-switches and arrow down to cabinet which would be defaulted to upright, using the arrow right button change cabinet from upright to cocktail, easy.
There is probably an easier way to do it so you don't have to adjust every game individually, I'm sure someone here will be able to tell you a better way to do it.
