The TurboDuo (later rebranded as simply the Duo) is a fourth-generation video game console developed by NEC Home Electronics and Hudson Soft for the North American market. It combines the capabilities of the TurboGrafx-16 and its CD-ROM drive add-on, the TurboGrafx-CD, into a single, redesigned unit. Initially test-marketed in Los Angeles in October 1992 before a nationwide rollout in May 1993,[2] TurboDuo is the localized version of the Japanese PC Engine Duo, which was released in September 1991.
Compared to TurboGrafx-16 and the TurboGrafx-CD, TurboDuo has an updated BIOS and 192 KB of additional RAM. The RAM increase and BIOS update afford the TurboDuo and PC Engine Duo compatibility with all CD-ROM² and Super CD-ROM² based software (Japanese and North American). Like the TurboGrafx-CD, the TurboDuo can read Compact Disc Digital Audio and CD+G discs. TurboDuo, however, cannot read PC Engine HuCards without modification or an adapter. With a HuCard adapter and an Arcade Card Duo, the TurboDuo can also read Arcade CD-ROM² games (which were sold only in Japan).
