The TurboGrafx-16, known as the outside North America, is a fourth-generation home video game console designed by Hudson Soft and sold by NEC Home Electronics. It was the first console marketed in the 16-bit era, although it used a modified 8-bit CPU. It was released in Japan in 1987 and in North America in 1989. The Japanese model was officially imported and distributed in France in 1989, unofficial imports had made their way to the UK by the same year, in 1990 Spain received a PAL version based on the American model known as simply TurboGrafx. In Japan, the system was launched as a competitor to the Famicom, but the delayed United States release meant that it ended up competing with the Sega Genesis and later the Super Nintendo Entertainment System. The TurboGrafx-16 has an 8-bit CPU, a 16-bit video color encoder, and a 16-bit video display controller. The GPUs are capable of displaying 482 colors simultaneously, out of 512. With dimensions of just 14 cm × 14 cm × 3.8 cm (5.5 in × 5.5 in × 1.5 in), the Japanese PC Engine is the smallest major home game console ever made. Games were released on HuCard cartridges and later the CD-ROM optical format with the TurboGrafx-CD add-on. The TurboGrafx-16 failed to break into the North American market and sold poorly, which has been blamed on the delayed release and inferior marketing. Despite the "16" in its name and the marketing of the console as a 16-bit platform, it used an 8-bit CPU, a marketing tactic that was criticized by some as deceptive. However, in Japan, the PC Engine, introduced into the market at a much earlier date, was very successful. It gained strong third-party support and outsold the Famicom at its 1987 debut, eventually becoming the Super Famicom's main rival. At least 17 distinct models of the TurboGrafx-16 were made, including portable versions and those that integrated the CD-ROM add-on. An enhanced model, the PC Engine SuperGrafx, was rushed to market in 1989. It featured many performance enhancements and was intended to supersede the standard PC Engine. It failed to catch on - only six titles were released that took advantage of the added power and it was quickly discontinued. The entire series was discontinued in 1994. It was succeeded by the PC-FX, which was released only in Japan.


The PC Engine was created as a collaborative effort between Hudson Soft, who created video game software, and NEC, a company which was dominant in the Japanese personal computer market with their PC-88 and PC-98 platforms. NEC lacked the vital experience in the video gaming industry and approached numerous video game studios for support. By pure coincidence, NEC's interest in entering the lucrative video game market coincided with Hudson's failed attempt to sell designs for then-advanced graphics chips to Nintendo. The two companies successfully joined together to then develop the new system. The PC Engine made its debut in the Japanese market on October 30, 1987, and it was a tremendous success. The PC Engine had an elegant, "eye-catching" design, and it was very small compared to its rivals. This, coupled with a strong software lineup and third-party support from high-profile developers such as Namco and Konami gave NEC a temporary lead in the Japanese market. The PC Engine sold 500,000 units in its first week of release. In 1988, NEC decided to expand to the American market and directed its U.S. operations to develop the system for the new audience. NEC Technologies boss Keith Schaefer formed a team to test the system. They found out that there was a lack of enthusiasm in its name "PC Engine" and also felt its small size was not very suitable to American consumers who would generally prefer a larger and "futuristic" design. They decided to call the system the "TurboGrafx-16", a name representing its graphical speed and strength and its 16-bit GPU. They also completely redesigned the hardware into a large, black casing. This lengthy redesign process and NEC's questions about the system's viability in the United States delayed the TurboGrafx-16's debut. The TurboGrafx-16 was eventually released in the New York City and Los Angeles test markets in late August 1989. Disastrously for NEC, this was two weeks after Sega of America released the true 16-bit Sega Genesis to test markets. Unlike NEC, Sega did not waste time redesigning the original Japanese Mega Drive system, making only slight aesthetic changes. The Genesis quickly eclipsed the TurboGrafx-16 after its American debut. NEC's decision to pack-in ''Keith Courage in Alpha Zones'', a Hudson Soft game unknown to western gamers, proved costly as Sega packed-in a port of the hit arcade title ''Altered Beast'' with the Genesis. NEC's American operations in Chicago were also overhyped about its potential and quickly produced 750,000 units, far above actual demand. This was very profitable for Hudson Soft as NEC paid Hudson Soft royalties for every console produced, whether sold or not. By 1990, it was clear that the system was performing very poorly and severely edged out by Nintendo and Sega's marketing. After seeing the TurboGrafx-16 suffer in America, NEC decided to cancel their European releases. Units for the European markets were already produced, which were essentially US models modified to run on PAL television sets and branded as simply "TurboGrafx". NEC sold this stock to distributors; in the United Kingdom Telegames released the TurboGrafx in 1990 in extremely limited quantities. This model was also released in Spain and Portugal through selected retailers. From November 1989 to 1993, PC Engine consoles as well as some of its add-ons were imported from Japan by French licensed importer Sodipeng (''Société de Distribution de la PC Engine'', a subsidiary of Guillemot International). This came after considerable enthusiasm in the French press. The PC Engine was largely available in France and Benelux through major retailers. It came with French language instructions and also an AV cable to enable its compatibility with SECAM television set. Its launch price was 1,790 French francs. Sodipeng went bankrupt in 1993. In the UK, the PC Engine was available as an unofficial imported machine. By March 1991, NEC claimed that it had sold 750,000 TurboGrafx-16 consoles in the United States and 500,000 CD-ROM units worldwide. In an effort to relaunch the system in the North American market, in mid-1992 NEC and Hudson Soft transferred management of the system in North America to a new joint venture called Turbo Technologies Inc. and released the TurboDuo, an all-in-one unit that included the CD-ROM drive built in. However the North American console gaming market continued to be dominated by the Genesis and Super NES, which was released in North America in August 1991. In May 1994 Turbo Technologies announced that it was dropping support for the Duo, though it would continue to offer repairs for existing units and provide ongoing software releases through independent companies in the U.S. and Canada. The final licensed release for the PC Engine was ''Dead of the Brain Part 1 & 2'' on June 3, 1999, on the Super CD-ROM² format.



The ''CD-ROM²'' is an add-on attachment for the PC Engine that was released in Japan on December 4, 1988. The add-on allows the core versions of the console to play PC Engine games in CD-ROM format in addition to standard HuCards. This made the PC Engine the first video game console to use CD-ROMs as a storage media. The add-on consisted of two devices - the CD player itself and the interface unit, which connects the CD player to the console and provides a unified power supply and output for both. It was later released as the ''TurboGrafx-CD'' in the United States in November 1989, with a remodeled interface unit in order to suit the different shape of the TurboGrafx-16 console. The TurboGrafx-CD had a launch price of $399.99 and did not include any bundled games. ''Fighting Street'' and ''Monster Lair'' were the TurboGrafx-CD launch titles; ''Ys Book I & II'' soon followed.

Super CD-ROM²

In 1991, NEC introduced an upgraded version of the CD-ROM² System known as the ''Super CD-ROM²'', which updates the BIOS to Version 3.0 and increases buffer RAM from 64kB to 256kB. This upgrade was released in several forms: the first was the ''PC Engine Duo'' on September 21, a new model of the console with a CD-ROM drive and upgraded BIOS/RAM already built into the system. This was followed by the ''Super System Card'' released on October 26, an upgrade for the existing CD-ROM² add-on that serves as a replacement to the original System Card. PC Engine owners who did not already own the original CD-ROM² add-on could instead opt for the Super-CD-ROM² unit, an updated version of the add-on released on December 13, which combines the CD-ROM drive, interface unit and Super System Card into one device.

Arcade Card

On March 12, 1994, NEC introduced a third upgrade known as the , which increases the amount of onboard RAM of the Super CD-ROM² System to 2MB. This upgrade was released in two models: the ''Arcade Card Duo'', designed for PC Engine consoles already equipped with the Super CD-ROM² System, and the ''Arcade Card Pro'', a model for the original CD-ROM² System that combines the functionalities of the Super System Card and Arcade Card Duo into one. The first games for this add-on were ports of the Neo-Geo fighting games ''Fatal Fury 2'' and ''Art of Fighting''. Ports of ''World Heroes 2'' and ''Fatal Fury Special'' were later released for this card, along with several original games released under the ''Arcade CD-ROM²'' standard. By this point support for both the TurboGrafx-16 and Turbo Duo was already waning in North America; thus, no North American version of either Arcade Card was produced, though a Japanese Arcade Card can still be used on a North American console through a HuCard converter.


Many variations and related products of the PC Engine were released.


The ''PC Engine CoreGrafx'' is an updated model of the PC Engine, released in Japan on December 8, 1989. It has the same form factor as the original PC Engine, but it changes the color scheme from white and red to black and blue and replaces the original's RF connector with an A/V port. It also used a revised CPU, the HuC6280a, which supposedly fixed some minor audio issues. A recolored version of the model, known as the ''PC Engine CoreGrafx II'', was released on June 21, 1991. Aside from the different coloring (light grey and orange), it is nearly identical to the original CoreGrafx except that the CPU was changed back to the original HuC6280.


The PC Engine SuperGrafx, released on the same day as the CoreGrafx in Japan, is an enhanced variation of the PC Engine hardware with updated specs. This model has a second HuC6270A (VDC), a HuC6202 (VDP) that combines the output of the two VDCs, four times as much RAM, twice as much video RAM, and a second layer/plane of scrolling. It also uses the revised HuC6280a CPU, but the sound and color palette were not upgraded, making the expensive price tag a big disadvantage to the system. As a result, only five exclusive SuperGrafx games and two hybrid games (''Darius Plus'' and ''Darius Alpha'' were released as standard HuCards which took advantage of the extra video hardware if played on a SuperGrafx) were released, and the system was quickly discontinued. The SuperGrafx has the same expansion port as previous PC Engine consoles, but requires an adapter in order to utilize the original CD-ROM² System add-on, due to the SuperGrafx console's large size.


The ''PC Engine Shuttle'' was released in Japan on November 22, 1989 as a less expensive model of the console, retailing at ¥18,800. It was targeted primarily towards younger players with its spaceship-like design and came bundled with a TurboPad II controller, which is shaped differently from the other standard TurboPad controllers. The reduced price was made possible by slimming down the expansion port of the back, making it the first model of the console that was not compatible with the CD-ROM² add-on. However, it does have a slot for a memory backup unit, which is required for certain games. The RF output used on the original PC Engine was also replaced with an A/V port for the Shuttle.


The ''PC Engine GT'' is a portable version of the PC Engine, released in Japan on December 1, 1990 and then in the United States as the TurboExpress. It can only play HuCard games. It has a backlit, active-matrix color LCD screen, the most advanced on the market for a portable video game unit at the time. The screen contributed to its high price and short battery life, however, which hurt its performance in the market. It also has a TV tuner adapter as well as a two-player link cable.


The ''PC Engine LT'' is a model of the console in a laptop form, released on December 13, 1991 in Japan, retailing at ¥99,800. The LT does not require a television display (and does not have any AV output) as it has a built-in flip-up screen and speakers, just as a laptop would have, but, unlike the GT, the LT runs on a power supply. Its expensive price meant that few units were produced compared to other models. The LT has full expansion port capability, so the CD-ROM² unit is compatible with the LT the same way as it is with the original PC Engine and CoreGrafx. However, the LT requires an adapter to use the enhanced Super CD-ROM² unit.


NEC Home Electronics released the ''PC Engine Duo'' in Japan on September 21, 1991, which combined the PC Engine and Super CD-ROM² unit into a single console. The system can play HuCards, audio CDs, CD+Gs, standard CD-ROM² games and Super CD-ROM² games. The North American version, the ''TurboDuo'', was launched in October 1992. Two updated variants were released in Japan: the ''PC Engine Duo-R'' on March 25, 1993, and the ''PC Engine Duo-RX'' on June 25, 1994. The changes were mostly cosmetic, but the RX included a new 6-button controller.

Third-party models

The ''PC-KD863G'' is a CRT monitor with built-in PC Engine console, released on September 27, 1988 in Japan for ¥138,000. Following NEC's PCs' naming scheme, the PC-KD863G was designed to eliminate the need to buy a separate television set and a console. It output its signals in RGB, so it was clearer at the time than the console which was still limited to RF and composite. However, it has no BUS expansion port, which made it incompatible with the CD-ROM² System and memory backup add-ons. The ''X1-Twin'' was the first licensed PC Engine-compatible hardware manufactured by a third-party company, released by Sharp in April 1989 for ¥99,800. It is a hybrid system that can run PC Engine games and X1 computer software. Pioneer Corporation's LaserActive supports an add-on module which allows the use of PC Engine games (HuCard, CD-ROM² and Super CD-ROM²) as well as new "LD-ROM²" titles that work only on this device. NEC also released their own LaserActive unit (NEC PCE-LD1) and PC Engine add-on module, under an OEM license. A total of eleven LD-ROM2 titles were produced, with only three of them released in North America.

Other foreign markets

Outside North America and Japan, the TurboGrafx-16 was released in South Korea by a third party company, Haitai, under the name ''Vistar 16''. It was based on the American version but with a new curved design. Daewoo Electronics distributed the PC Engine Shuttle into the South Korean market as well.

Technical specifications

The TurboGrafx-16 uses a Hudson Soft HuC6280 CPU—an 8-bit CPU modified with two 16-bit graphics processors—running at 7.6 MHz. It features 8 KB of RAM, 64 KB of Video RAM, and the ability to display 482 colors at once from a 512-color palette. The sound hardware, built into the HuC6280 CPU, includes a PSG running at 3.58 MHz and a 5-10 bit stereo PCM. TurboGrafx-16 games use the HuCard ROM cartridge format, thin credit card-sized cards that insert into the front slot of the console. PC Engine HuCards feature 38 connector pins, while TurboGrafx-16 HuCards (alternatively referred to as "TurboChips") feature eight of these pins in reverse order as a region lockout method. The power switch on the console also acts as a lock that prevents HuCards from being removed while the system is powered on. The European release of the TurboGrafx-16 did not have its own PAL-formatted HuCards as a result of its limited release, with the system instead supporting standard HuCards and outputting a PAL 50 Hz video signal.


The TurboGrafx-16 controller, officially named the TurboPad, features a rectangular shape with a directional pad, two numbered "I" and "II" buttons, two rubber "Select" and "Start" buttons, and two "Turbo" switches for the I and II buttons with three speed settings. The switches allow for a single button press to register multiple inputs at once (for instance, this allows for rapid fire in scrolling shooters). The TurboGrafx-16 only has one controller port; NEC later released a peripheral named the TurboTap, which plugged into the port on the system and allowed for five other controllers to be plugged in at once for multiplayer games. Many peripherals were produced for the TurboGrafx-16. The TurboStick is a joystick designed to replicate the standard control layout of arcade games from the era. The controller features a bright-red joystick, two input buttons, turbo switches, and two buttons that can speed up or slow down the framerate in games. Other similar joystick controllers were produced by third-party manufacturers, such as the Python 4 by QuickShot and the Stick Engine by ASCII Corporation. The TurboCable is an extension cable that increased the length of the TurboPad's wire length, allowing the system to be played from a further distance. The TurboBooster inserted into the back of the system and allowed it to render better visual and audio quality through composite cables. Hudson released the Ten no Koe 2 in Japan, which enabled the ability to save player progress in HuCard games.


A total of 686 commercial games were released for the TurboGrafx-16. In North America, the system featured ''Keith Courage in Alpha Zones'' as a pack-in game, which was absent from the PC Engine. The console received strong third-party support in Japan, while the TurboGrafx-16 struggled to gain the attention of other developers. Hudson brought over many of its popular franchises, such as ''Bomberman'', ''Bonk'', and ''Adventure Island'', to the system with graphically-impressive follow-ups. Hudson also designed and published several original titles such as ''Air Zonk'' and ''Dungeon Explorer''. Compile published ''Alien Crush'' and ''Devil's Crush'', two well-received virtual pinball games. Namco contributed several high-quality conversions of its arcade games, such as ''Valkyrie no Densetsu'', ''Pac-Land'', and ''Splatterhouse'', as did Capcom with a port of ''Street Fighter II''. A large portion of the TurboGrafx-16's library is made up of horizontal and vertical-scrolling shooters. Examples include Konami's ''Gradius'' and ''Gradius II'', Hudson's ''Super Star Soldier'' and ''Soldier Blade'', Namco's ''Galaga '88'', Irem's ''R-Type'', and Taito's ''Darius Alpha''. The console is also known for its platformers and role-playing games; Victor Entertainment's ''The Legendary Axe'' won numerous awards and is seen among the TurboGrafx-16's definitive titles. ''Ys I & II'', a compilation of two games from Nihon Falcom's ''Ys'' series, was particularly successful in Japan. Cosmic Fantasy 2 was an RPG ported from Japan to the United States that earned Electronic Gaming Magazine RPG of the year in 1993.


In Japan, the PC Engine was very successful, and at one point it was the top-selling console in the nation. In North America and Europe the situation was reversed, with both Sega and Nintendo dominating the console market at the expense of NEC. Initially, the TurboGrafx-16 sold well in the U.S., but eventually it suffered from lack of support from third-party software developers and publishers. In 1990, ''ACE'' magazine praised the console's racing game library, stating that, compared to "all the popular consoles, the PC Engine is way out in front in terms of the range and quality of its race games." Reviewing the Turbo Duo model in 1993, ''GamePro'' gave it a "thumbs down". Though they praised the system's CD sound, graphics, and five-player capability, they criticized the outdated controller and the games library, saying the third party support was "almost nonexistent" and that most of the first party games were localizations of games better suited to the Japanese market. In 2009, the TurboGrafx-16 was ranked the 13th greatest video game console of all time by IGN, citing "a solid catalog of games worth playing," but also a lack of third party support and the absence of a second controller port. The controversy over bit width marketing strategy reappeared with the advent of the Atari Jaguar console. Mattel did not market its 1979 Intellivision system with bit width, although it used a 16-bit CPU.


In 1994, NEC released a new console, the Japan-only PC-FX, a 32-bit system with a tower-like design; it enjoyed a small but steady stream of games until 1998, when NEC finally abandoned the video games industry. NEC supplied rival Nintendo with the RISC-based CPU, V810 (same one used in the PC-FX) for the Virtual Boy and VR4300 CPU for the Nintendo 64, released in 1995/1996, and both SNK updated VR4300 CPU (64-bit MIPS III) on Hyper Neo Geo 64, as too former rival Sega with a version of its PowerVR 2 GPU for the Dreamcast, released in 1997/1998. A number of TurboGrafx-16 and TurboGrafx-CD games were released on Nintendo's Virtual Console download service for the Wii, Wii U, and Nintendo 3DS, including several that were originally never released outside Japan. In 2011, ten TurboGrafx-16 games were released on the PlayStation Network for play on the PlayStation 3 and PlayStation Portable in the North American region. In 2010 Hudson released an iPhone application entitled "TurboGrafx-16 GameBox" which allowed users to buy and play a number of select Turbo Grafx games via in-app purchases. In 2016, rapper Kanye West's 8th solo album was initially announced to be titled "Turbo Grafx 16". The title, however, was later changed to Ye. In 2019, Konami announced at E3 2019 the TurboGrafx-16 Mini, a dedicated console featuring many built-in games. It's the first release of official hardware of the TurboGrafx-16 family since the closure of Hudson Soft in 2012. On March 6, 2020, Konami announced that the TurboGrafx-16 Mini and its peripheral accessories will be delayed indefinitely from its previous March 19, 2020, launch date due to the COVID-19 outbreak in China. It was released in North America on May 22, 2020 and released in Europe on June 5, 2020.
