If it doesn't register, then you're SOL.
I should have come in here sooner. This isn't true.
How many joysticks are on your system? Go into Gamepads and see how many are registered. Daphne will want to use the first one in the list. However, you can make it use any one you want.
This is from memory... but try it out. Go into your gamepad list in the control panel. Highlight the GPWiz and click the "Advanced" button. Set the preferred device to your GPWiz.
Bam. Daphne should see it.
The only thing Daphne can't do is use more than one gamepad device at once. So if you have GPWiz and a flightstick, you can't have Daphne see them both. Or, like on my system, I have my preferred device set as my U360, but then I don't get the admin buttons that are on my GPWiz. I've got to use joy2key for those.
