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.
