I would think these are handled the same because in Windows they're both gamepads, right?
Anyways, I remember a while back people having to use joytokey for this or something? But last night, when I was playing DL in Daphne, I thought to use my U360 and it just worked. I don't have it harnessed to my I-PAC.
So I guess it works now, and thought I'd mention in case it was news.....
