PS3 Controllers

So I have various concerns. But initially I am capable of connect a PS3 controller employing an OTG cable and it worked from the box absolutely nothing else wanted. My questions are:

Is it doable for that PS3 remote controller to wirelessly connect towards the Nexus? I don't would like to root my gadget though' because yes I've heard of Sixaxis.

2nd. Has any person had any luck acquiring the controller to get the job done on video games like Contemporary Combat 3 or NOVA 3? For me, the games register the controller but none with the buttons are correct to FPS layouts as well as the joysticks usually do not operate whatsoever. (I are unable to move)
