I’ve tried RecalBox lately. The PS3 controller works like a charm with it. It’s a very nice approach, but the system is kind of close, you can’t modify much like in the retropie distro, so I came back to it.
When you connect a PS3 controller with RecalBox you only have to wait about 5secs and disconnect the usb cable. After that you are able to connect the controller with ease every time.
