Strange things, i dont even know where to start, but i will drop RetroPie until it will be 3.0 Stable.

It looks like via usb cable – pad works, if i want to pair it via BT – it gets paired ok but it wont work in emustation or in games.

ok, edit:

just found ./retroarch-joyconfig did whole config via BT and pad works it was paired but somekind emustation cant see those configs
