What we've got here is an old Fist of the North Star game for the Genesis that was released in America as Last Battle. I am of the opinion that this game is impossible to beat, as I've only ever managed to make it to the beginning of the 3rd world, and I'm told that the 4th world makes everything before it look like cake.
