              Also known as the game everyone uses to calibrate their 5200
                joysticks, the Atari 5200 version of Missile Command is a direct
                port of the Atari 400/800 version except that the Atari
                copyright is missing from the title screen.  This is
                because the Atari 5200 already has a separate splash screen
                which displays the copyright before the game starts. 
                Although Atari could have redesigned the game to take advantage
                of the 5200's second fire button and keypad to closer imitate
                the controls of the arcade game, they chose to release the
                400/800 version instead.Interestingly a PAL prototype version of 5200 Missile
                  Command has been found.  While the 5200 was never
                  released in PAL territories, this prototype proves that it was
                  indeed planned for release overseas.  The PAL 5200
                  version of Missile Command is the same as the NTSC version but
                  with the scanlines and timings adjusted for PAL TVs. |
