Hello, I’m having this problem too. It seems my fake PS3 controllers are now found as “Sony PLAYSTATION ® 3 Controller” via bluetooth, as opposed to “SHANWAN PS3 GAMEPAD”. The only issue I have noticed with this change is the vibration doesn’t work correctly.
When connected by USB cable the controller is found as SHANWAN and the vibration works correctly. The same controller connected by bluetooth is found as Sony PS3 controller and vibration is porked.
I have changed the PS3 driver in batocera.conf from bluez to shanwan, and rebooted, but that hasn’t resolved it. The fake PS3 controller still shows as Sony PS3 Controller as opposed to SHANWAN via bluetooth.
