Ninja Ryukenden for PC-Engine was released on January 24, 1992 in Japan for 6500 Yen.
This PC Engine version is a port of Ninja Ryukenden originally released for the Famicom in 1988. The conversion features enhanced graphics, a parallax scrolling and a totally different soundtrack. Enemy placements are also slightly different and although the levels layout is fairly similar, most of the backgrounds were redesigned. Curiously, some of the character names were also changed - for instance, Ken Hayabusa was surprisingly renamed Joe Hayabusa. Interestingly, an option in the game's menu allows the player to change the cut scenes from Japanese (default) to English and Chinese (see the Tips section).
