You may have to configure each button manually. Config => Gampad => Port 1 => pad 1 and a picture will pop up of a controller, click on each button and then press the corresponding one on your controller to map it and hit ok when done.
Also keep in mind that older games were digital only before the dual shock came out - when in game you can switch between digital and analog with F5 (you can also change it in the options as well)
