Original System: Atari 5200

Port of the 1982 Sega arcade game, Pengo is a cute action game with some puzzle strategy thrown in.  The 5200 and 400/800 ports are very similar, but the there are two changes.  First, the title screen is missing the # and 0 in front of each option in the 400/800 port since the 400/800 didn't use those keys for changing options (it used Select and Option).  Secondly the game music uses two voices in the 5200 version and only one in the 400/800 port.  This is assumed to be a bug as there's no reason that it would have been changed as both systems use the exact same sound chip.
