options - key configuration

hi guys...just got myself this awsome game..i have problems with controls - i'm using logitech gamepad, but seems the game doesn't recognize it...when i go to multiplayer - split screen, it says: press Y to join. i'm pushing all buttons, but nothing happens...any idea? then, i'm wondering if it is possible to manually configuare keys - there are just 2 options, i would like to change key as i want - is it possible? thanx
