What is mario kart pc?

As an AI language model, I don't have any specific information about the PC version of Mario Kart as it doesn't officially exist. However, Mario Kart is a popular kart racing game developed and published by Nintendo for its consoles like Nintendo Switch, DS, Wii, and Wii U. There are also various unofficial fan-made PC versions of the game available. These fan-made versions of the game are not supported or endorsed by Nintendo, and players use emulators to run them on their PC. These fan-made versions of the game aim to provide an experience similar to the original game with additional features such as online multiplayer, new characters, and tracks. However, playing or downloading these fan-made versions is often illegal and can pose a security risk to players' devices.
