|The Atari 400/800 version starts with a simple
title screen showing the Pac-Man logo Atari copyright
while the 5200 version goes straight to the options
screen. The 5200 has its own splash screen so it
doesn't need to show this.
The options screen on the Atari 400/800 version
doesn't show 00 for the default high score and the text
is a darker shade of white
|The options screen on the Atari
400/800 version has 'Press Select' instead of 'Press 1-2
Player' and 'Press Option' instead of 'Press Game Level'
to change the options. There are no '1-2 Player' or
'Game Level' buttons on the 5200 controller however and
these options are changed with the * and # keys.
|The 5200 version adds an easter egg on the title
screen that's accessed by spelling out Pac-Man on the
keypad (0722626). Doing so will change the "Press
Start to play game" text to "By James Andreasen".
James Andreasen was the programmer who updated the 5200
|The Atari 5200 version has all the intermissions
while the 400/800 version has none. There is new
music added for the intermissions.
|In the 5200 version Pac-Man starts each level with
his mouth open while it's closed in the 400/800 version
|In the 5200 version there's a sound for scoring an
extra life at 10,000 points
|The 5200 version plays faster than the 400/800
version making the speed much closer to the arcade version
