I made some clunky drivers that works with the chatpad and wired 360 controller to emulate a keyboard (and optional mouse with the thumbsticks), but I haven't tried to reverse engineer the wireless controller yet. =( It's been like a year or two that that particular project has been in limbo.Unrelated but do these work on PC? :lol
