This game is known in Japan as "Hokuto no Ken - Shinseiki Matsu Kyuuseishu Densetsu" (translates from Japanese as 'Fist of the North Star - Waiting For The Savior of the New Century').
This game is based on the manga 'Hokuto no Ken' by Buronson and Tetsuo Hara. 'Hokuto' is the Japanese word for the constellation known in the west as 'The Big Dipper'. This is why the main character, Kenshirou, has seven scars in the shape of the big dipper on his chest, not just one scar representing the north star.
Changes from Japanese version :
Blood removed, Enemies now just fly off screen instead of exploding.
All characters are recolored.
Characters were all given stupid names. Kenshirou became Aarzak, Bat became Max, Lin became Alyssa, etc.
Chapter titles removed.
