I tried both, but they didn't work.
Both ways will add the device in the game control devices list, but it will say 'not connected' no matter what I do. Even though I have the latest Xperience drivers.
(The windows site recommended to add it as a joypad with 4 buttons, but how should I play PSX that way? )
It's an integrated soundcard, but I'm pretty sure it's a problem that has got something to do with SP2. Are you suggesting I should reïnstall sound drivers? (I'm quite confident that that isn't the problem)
