ps3 controller issues on osx snow leopard

So I installed snes9x for my iMac running snow leopard and have paired my ps3 controller for my game controller. When I go to configure my controller all my buttons pair up easy and I see that the config window detects it as well. So when I go to play a game on the emulator nothing works. No response at all. I have tried everything I can think of. Why would I see my controller working ok in the configure window and not work during a game? Any help would be appreciated. Thank You.
