My cab is a cocktail, each side has a Neo geo 4 button config. Each side also has a start and a pause.... On side back side above the key locked access door is another keylocked door. Behind that door is a red hepp button , I use this the mame menu button, With my shift key (player1 start) it is also "player1 coin or 5" beside that is 2 yellow happ button for system volume. Shifted Save/Load state. Next to them is a black Rod Switch for F2 service button. And finally beside that is a red micro switch for PC power and a Black Micro for PC reset.... To exit I set it be Shift Player 1 pause....... Hope that helps , by doing it that way I have a very clean look....... ML
