Atari 2600[edit]
AtariAge.com forum member PacManPlus is a programmer who is largely responsible for converting many versions of Pac-Man on various Atari platforms in to Pac-Man Plus. In this case, he took Rob Kudla's Ms. Pac-Man hack known as Mr. Pac-Man, and further hacked it into Pac-Man Plus. Meanwhile, forum member Nukey Shay has been diligently hacking the core of Ebivision's Pesco ROM for the 2600 in to Pac-Man, and added the variations contained in Pac-Man Plus, (as well as Hangly-Man, a bootleg variant of the original) in to the program.
Atari 5200[edit]
PacManPlus took the well received conversion of Pac-Man for the Atari 5200 (and the Atari home computers) and hacked it in to Pac-Man Plus with a great deal of success. This conversion also changes the Atari logo back to the Galaxian Flagship.
Atari 7800[edit]
PacManPlus has also hacked the original Atari 7800 Ms. Pac-Man ROM into not only Pac-Man, but a number of Pac-Man-related projects, including Pac-Man Plus, Hangly-Man, Ms. Pac-Attack, (a hack of the original Ms. Pac-Man arcade game that altered the maze layouts), and a multiple maze version called Ultra Pac-Man. He has collected all of these hacks into one cartridge entitled Pac-Man Collection. PacManPlus has done more than just alter the maze and colors, he has also updated the graphics and taken many beta testers' suggestions into consideration, to make the most accurate conversion possible.
Colecovision[edit]
Opcode Games, developer of new titles for the Colecovision system, has developed a homebrew cartridge that includes versions of original Pac-Man and Ms. Pac-Man, with the aim of making them as faithful to the original arcade versions as they can possibly be. As a bonus, Pac-Man Plus is available as a hidden game on the cartridge. Despite limitation upon the display resolution permitted by a television set, the conversions are considered to be quite accurate, and well made.
