This system was released in Japan as the PC Engine in 1987, and in North America in 1989. It featured an 8-bit CPU and 16-bit graphics, giving it superior visual performance over the NES with which it originally competed. With a head-start in the 16-bit market and the support of major Japanese game makers, the PC Engine continued to do well in Japan against Nintendo's Super Famicom and Sega's Megadrive, but the TurboGrafx-16 struggled in North America, probably due to the larger number of game titles available for SNES and Genesis. Also both Nintendo and Sega offered multiplayer support out of the box, but the TurboGrafx included only one controller port.
