Just recently got a good working Batocera install on a Lenovo M73 tiny. It's an i5 4570t with 8GB ram and just intel integrated graphics. I'm impressed so far by the integrated graphics. I'm running dreamcast without issue now. I have a bluetooth dongle but when I go to pair bluetooth controller from the menu, it just times out. Is there something special I need to do for the OS to recognize my dongle? Maybe it's just not compatible?
