A lot of games have jerky scrolling. Fixing this would be a definite improvement but would be non-trivial. Some have worse scrolling than others. Rolling Thunder, Barbarian (Psygnosis), Pac-Land, Quadralien, Bionic Commando and Alien Syndrome spring immediately to mind.
Just think to some games that could be better with some little fixes, of course I'm not talking about Rise of the robots
Rise of the Robots just needs a small gameplay tweak to make the flying kick not so good, then it would be an awesome game.
