Super Breakout
The 5200 version (pictures #3 and #4) is actually a modified version of the 400/800 version (pictures #1 and #2). Besides having a larger playfield area, colors, and copyright date, the arcade-like sound effects of the 400/800 version have been replaced. Also, the blocks melt away when hit, instead of simply disappearing.
Pressing 1 during a game will give you 5 extra serves!
RUMOR: Is the hidden message from the 400/800 version (picture #2) in this version?
