Video game conversion
In video gaming parlance, a conversion is the production of a game on one computer or console that was originally written for another system. The general software term for this is porting. 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.
In the arcade video game industry, the term conversion has a different meaning, referring to game conversion kits for arcade cabinets.
