The TurboDuo was a video game console released in the United States, as an updated variant of the PC Engine (known as TurboGrafx-16 in North America). It was released on October 10, 1992 by Turbo Technologies Incorporated, a Los Angeles-based corporation consisting of NEC and Hudson Soft employees, established to market NEC consoles in North America after NEC Home Electronics USA failed to effectively market the platform. The Japanese counterpart was the PC Engine Duo game console, which was released over a year earlier.
The TurboDuo is essentially a combination of TurboGrafx-16 and TurboGrafx-CD hardware, plus the Super System BIOS and an extra 192k of RAM built into the motherboard. The TurboDuo was capable of playing standard audio CDs, CD+Gs, TurboGrafx TurboChips, and Japanese and North American CD-ROM² (TurboGrafx-CD) and Super CD-ROM² titles. The system is able to play Japanese PC Engine HuCards with a third party HuCard converter or modification. With a HuCard converter plus a Japanese Arcade Card Duo, the system can also play Japanese Arcade CD-ROM² games.
