"A supported Bluetooth device could not be found. You must manually connect your Wiimotes." Even though it says this it still works when everything is synced. I don't have any other bluetooth devices. The Dolphinbar is the only one.
Resolved. After testing another Wiimote it is determined that the one I received had broken rumble.
Latest dev build of Dolphin and 5.0 do not recognize my bluetooth when connected and synced on LED 4. Wiimote does not rumble when pressing Refresh. Even so, it still works in game and on home menu.
