In porting arcade games, the terms "arcade perfect" or "arcade accurate" were often used to describe how closely the gameplay, graphics, and other assets on the ported version matched the arcade version. Many arcade ports in the early 1980s were far from arcade perfect as home consoles and computers lacked the sophisticated hardware in arcade games, but games could still approximate the gameplay. Notably, "Space Invaders" on the Atari VCS became the console's killer app despite its differences, while the later "Pac-Man" port was notorious for its deviations from the arcade version. Arcade-accurate games became more prevalent starting in the 1990s, starting with the Neo Geo system from SNK, which offered both a home console and an arcade system with more advanced versions of the home console's main hardware. This allowed near-arcade perfect games to be played at home. Further consoles such as the PlayStation and Dreamcast, also based on arcade hardware, made arcade-perfect games a reality.
