brkthru, brkthruj and brkthrut have a Self Test Mode not mentioned anywhere
in the manual. It is accessed by holding down both player 1 and player 2 start
buttons while powering up the game. It can be accessed in MAME by holding the
buttons down after the game has started then pressing F3 to reset the game.
