Over the years, video game conversion has taken form in a number of different ways, both in their style and the method in which they were converted.
While the game was fundamentally the same, the title, names, graphics and audio were usually changed to avoid legal challenges.
This was a particular phenomenon during the late 1990s with numerous 3D updates of games such as Frogger, Missile Command, Asteroids and Space Invaders.
For example, a conversion kit can be used to reconfigure an arcade machine designed to play one game so that it would play its sequel or update instead, such as from Street Fighter II: Champion Edition to Street Fighter II Turbo.
Atari produced their own "official" conversion of the game for home use, but a number of other imitators such as Sears' Telegames Pong IV were also on the market.
Later, other third-party developers and publishers such as Activision and Coleco produced games like Donkey Kong for the Atari 2600.
