Original: Arcade · 1980
Pac-Man's 1982 Atari 2600 port is one of the most notorious conversions in gaming history — a rushed, technically compromised release that contributed to the 1983 video game crash by failing to meet the expectations of consumers who paid full price expecting an arcade-quality experience.
Pac-Man was the best-selling arcade game of all time by 1981, and Atari paid Namco a substantial licensing fee for the home rights, marketing the 2600 version as "the arcade game for your home" in television advertising. The port, programmed by Tod Frye under a strict six-month deadline, made significant compromises due to the 2600's 128 bytes of RAM and the hardware's inability to display multiple sprites on the same horizontal line: the four ghosts flickered severely as the game rapidly cycled through their sprites, the maze was redesigned to be less faithful to the arcade layout, and the power pellets were reduced to two. The game sold approximately seven million copies — making it the best-selling Atari 2600 game by units — but was widely perceived as falling short of its marketing promises. Atari had manufactured twelve million cartridges in anticipation of demand, leaving five million unsold and contributing to the financial crisis that helped precipitate the 1983 industry crash.
The 2600 port required severe compromises due to the hardware's 128 bytes of RAM and sprite limitations: the four ghosts flickered constantly as the system cycled through their display, the maze was redesigned, and the game bore only a loose visual resemblance to the arcade. It sold seven million copies but generated widespread consumer disappointment.
The 5200 version was a substantially more faithful conversion, benefiting from the more capable hardware and running at a frame rate and visual quality much closer to the arcade original. It is rarely remembered because the 5200 had a smaller install base than the 2600.
The NES version by Namco was a competent port that reproduced the maze faithfully and ran without the sprite flickering that plagued the 2600 version, benefiting from the NES's superior graphics hardware. It was widely accepted as the standard home version of Pac-Man for most of the 1980s.
Multiple C64 versions existed; the most widely distributed reproduced the maze and ghost behaviour accurately with minimal flickering due to the C64's sprite hardware. It was considered a better version than the Atari 2600 port by contemporary reviewers.
