As far as using the PS3 and Wii controllers all together on one system with no conflicts, you have to use two bluetooth adapters and they both must be different adapters, not the same. On Dolphin I use the "Real Wiimote" setting for one adapter. The adapter that I found for the Wii controller use is a cheap 4.0 bluetooth adapter on ebay, nothing fancy. The PS3 controllers run off of an Insignia bluetooth adapter from Best Buy. The PS3 controllers run off of ScpToolkit, which modifies the bluetooth adapter to exclusively work with only PS3 controllers. Both bluetooth adapters work perfect together and connect PS3 and Wii controllers separately with no interference.
