The Fujitsu FM Towns Marty is a console from the fifth generation of video game consoles. Based on the software library of the FM Towns PC, the console was launched in Japan on February 20, 1993 and never saw a global release. A variant — the FM Towns Car Marty — was designed to be installed in an automobile and included a built in navigation system with audio and video guidance, and could also be detached from the car and played at home. Marty is more of a computer rather than a console and sported several excellent arcade ports as well as IBM DOS ports. Marty is unique compared to FM Towns computer as it has 'pad-to-mouse' emulation in the BIOS reducing the need for owning a mouse. Some games however aren't compatible with 'pad-to-mouse' emulation and require the original mouse. Marty unfortunately has S-video and Composite as the only available video output.
