You do need to duplicate the environment to get the correct look and feel of the games, and this usually includes both control and display tech; and some it’s more critical than others. Try playing Marble Madness without a large trackball or Pac-Man with an analog joystick and you’ll find things just aren’t right with the controls. Display is similar, many games took artifacting and the imperfections of old tech to their advantage. Our old games weren’t played with chunky, sharply-defined pixels, but more of softer, blended pixels that were often smoothed out.
