The title GTA, also known as Grand Theft Auto 1, was originally developed in DOS, but was later ported to Microsoft Windows, Sony PlayStation and Game Boy Color versions. Grand Theft Auto was also to be released on Sega Saturn, but due to problems due to the rapid decline to which the console was destined, the project was cancelled. After the success of the PlayStation GTA version, the developers decided to start a new porting for the Nintendo 64 version, Grand Theft Auto 64, whose graphic improvements and new missions included were noisy, but was deleted without any appearance in public.
