I don't have it mounted on a cab yet , i am trying to make a spin 180 panel with the robotron two joystick panel. I really like robotron. I us to use the 2 player start button for one player start and the yellow ( inviso ) button for 2 player start , for the other games , until i put the two together , now the start buttons are on the robo panel , i started to drill another hole to replace player 1 start button , if the spin doesn't work i might still do that. i use player 1 start for move left , the next red button for move right , the three other buttons yellow for inviso , red for shield , but a friend only put the yellow button , he doesn't mind using the yellow for inviso and shield , for me that makes the shield button too far to the left , i like it where it should be , so when i play my buddies cocktail space duel the buttons are where i am use to and of-course the green button stays smart bomb , I hope this helps
