From Wikipedia The success of [Breakout] resulted in the development of Super Breakout a couple of years later. While ostensibly very similar to Breakout, the layout, sound, and general behavior of the game is identical. Super Breakout is a microprocessor based game instead of discrete logic, programmed by Asteroids programmer Ed Logg using an early M6502 chip. Super Breakout can therefore be emulated in MAME and is also featured in a number of different Atari compilation packs. The original Breakout has not been featured, since there is no processor in Breakout, the game would have been more "simulated" than emulated. In Super Breakout, there are three different and more advanced game types from which the player can choose: * Double gives the player control of two bats at the same time, one placed above the other, and two balls. Losing a life occurs only when both balls go out of play, and points are doubled while the player is able to juggle both balls without losing either. * Cavity retains the single bat and ball of Breakout, but two other balls are enclosed on the other side of the wall, which the player must free before they, too, can be used to destroy additional bricks. Points are increased for this, but triple points are available if the player can keep all three balls in play. * Progressive also has the single bat and ball, but as the ball hits the paddle, the entire wall gradually advances downwards step by step, gaining in speed the longer the ball lasts in play.
