i think adair might be talking about the emus having problem with that particular game, which is possible.
hmm, if you updated the drivers successfully, the one in "gaming options" should be the new one, they might just have the same name. try unplug it, restart, and plug it back in.
also, do you have another game to try this with?
also try different emus. which one are you using anyways? for example, so far the only emu with vibration is epsxe, i think.
