Famicom 3D System
The Famicom 3D System is a Famicom expansion port device that uses active LCD shutter glasses to provide 3D visuals. The headset (HVC-031) plugs into a control box (HVC-032) using a 3.5mm connector. The control box has two such ports, allowing up to two headsets, and passes through a Famicom expansion port so other controllers can be used. Compatible games manually control which eye sees which frame, alternating to give each eye a unique perspective that creates a 30 Hz stereoscopic image. While these glasses do not require a CRT TV to correctly function, modern TVs without very low latency and some kind of impulse display, such as black frame insertion, may not be compatible.
The 3D System is supported by the following Famicom games:
- Attack Animal Gakuen (1987)
- Cosmic Epsilon (1989)
- Falsion (1987)
- Famicom Grand Prix II: 3D Hot Rally (1988)
- Fuuun Shourin Ken: Ankoku no Maou (1988)
- Highway Star (1987)
- JJ: Tobidase Daisakusen Part II (1987)
- Tobidase Daisakusen (1987)
In these games, the 3D mode can be toggled with the select button except in Fuuun Shourin Ken: Ankoku no Maou, where the mode is enabled by holding A while pressing start on the title screen.
Note that the 3D System was only released in Japan. Versions of these games released internationally (3-D WorldRunner and Rad Racer) instead achieve 3D with an anaglyph mode using passive red and cyan glasses.

Because the Famicom only generated images at 60Hz, each resultant image will flicker at 30Hz.
