Ranma 1/2: Datou, Ganso Musabetsu Kakutou Ryuu!PC-Engine Super CD2 Japanese (NTSC-J) Games
This is a side scrolling 2D fighter that follows a popular anime series in Japan. It's got the usual Japanese quirks to it, like pictures of girls in bikinis and whatnot on it, but it's a pretty decent like fighting game!
