The PC-FX (ピーシー エフエックス Pī Shī Efu Ekkusu) is a 32-bit home video game console made by NEC Corporation. It was released in Japan on December 23, 1994, just weeks after Sony's PlayStation and a month after the Sega Saturn. It is the successor to NEC's PC Engine, known as TurboGrafx-16 in North America.

Unlike its predecessor, the PC-FX was only released in Japan. The console is shaped just like a tower PC and was meant to be similarly upgradeable. However the PC-FX was using an outdated graphics chip that made the system underpowered. A lack of developers' support also meant inadequate games and as a result it was unable to compete effectively with its fifth generation peers. The PC-FX was NEC's last home video game console, and was discontinued in February 1998.


NEC launched the PC-FX's predecessor, the PC Engine in 1987, which although had been warmly accepted in Japan, was unable to match the technical specifications put forward by Nintendo and Sega with their consoles, the Super Famicom and the Sega Mega Drive. Plans were therefore drawn up by NEC for a successor in order to reclaim lost ground.

The PC-FX was based on a 32-bit system architecture named "Iron Man", developed in-house by NEC. NEC demonstrated Iron Man at a number of trade shows and events during 1992, and by the middle of the year were discussing an imminent release of an Iron Man-based video game system with many third party developers. At the time, the earlier PC Engine was still quite popular in Japan, and opinions on the Iron Man technology were mixed. Many were uninterested in switching to more powerful hardware while the PC Engine market was still growing, and as a result NEC halted work on the Iron Man project, instead opting for more modifications to the PC Engine technology.

When NEC decided to release the PC-FX, the specs were relatively unchanged from the originally unveiled Iron Man architecture. The most significant difference was the addition of a new 32-bit V-810 RISC CPU.[3]

The console was announced in late 1993.[3][4] In a special Game Machine Cross Review in May 1995, Famicom Tsūshin would score the PC-FX console an 18 out of 40.[5]

Unusual for a fifth generation console, the PC-FX does not have a polygon graphics processor.[6][7] The shining quality of the PC-FX was the ability to decompress 30 JPEG pictures per second while playing digitally recorded audio (essentially a form of Motion JPEG).[7] This resulted in the PC-FX having superior full motion video quality over all other fifth generation consoles.

Unlike nearly any other console (except for the 3DO and CD-i), the PC-FX was also available as an internal PC card for NEC PC-98 and AT/IBM PC compatibles. This PC card came with two CDs of software to help the user program games for the PC-FX. However, compatibility issues prevented games developed with this software from actually running on the console.

The PC-FX was discontinued in early 1998. According to NEC of Japan, the PC-FX had sold just under 100,000 units.[2]


The system uses standard S-video and composite A/V ports.

The PC-FX uses CD-ROMs as its storage medium, following on from the expansion released for its predecessor, which originally used HuCards. The game controller is virtually identical to a DUO-RX controller, but the rapid fire switches have been replaced with mode A/B switches. Peripherals include a PC-FX mouse, which is supported by strategy games like Farland Story FX and Power DoLLS FX.

The PC-FX's computer-like design was unusual for consoles at the time. It stands upright like a tower computer while other contemporary consoles lay flat. Another interesting feature is its three expansion ports.

The PC-FX includes an HU 62 series 32-bit system board, an LSI chip, and a 32-bit V-810 RISC CPU. The system can display 16.77 million colors (the same amount as the Playstation).[3]


There were 62 games released for the system. The launch titles were Graduation 2: Neo Generation FX, Battle Heat and Team Innocent on December 23, 1994 and the final game released was First Kiss Story on April 24, 1998. The system and all titles were only released in Japan. A number of demo discs were also released with publications which allowed the user to play the disc in a CD equipped PC-Engine or the PC-FX.

There was no copy protection on any of the PC-FX games, because at the time the system was released, the high price of CD-R burners made piracy expensive.
