F1 (video game)

F1 (released as Formula One in the USA) is a 1993 racing video game published by Domark, based on Vroom!, a game developed in 1991 for the Atari ST by French company Lankhor. It was released for the Mega Drive/Genesis, Master System, Game Gear, and Amiga. It spawned a sequel in 1994 titled F1 World Championship Edition, and the game engine was reused in Kawasaki Superbike Challenge. It was one of the most popular racing games in the console, mostly thanks to the smooth and fast game engine

There are no major differences between the European and North American Sega versions, except naming (The European version is simply named F1), and the lack of battery save in the American version.

F1 (classification)

F1, also T1 and SP1, is a wheelchair sport classification that corresponds to the neurological level C6. Historically, it was known as 1A Complete. People in this class have no sitting balance, and are tetraplegics. They may be able to perform limited actions with one hand. They lack sitting balance, and have limited head control and respiratory endurance. The process for classification into this class has a medical and functional classification process. This process is often sport specific.
