No its not with only one emulator
Anyone who has a solution? :(

@smoothmalik If bluetoothct1 is not present, it means retropie is still using BlueZ 4, to my knowledge you won't be able to run both PS3 and PS4 controllers at the same time with this kind of setup. Perhaps you should open an issue about that on retropie's github

@Obmug If using a rpi3, you will do better to use lr-mame2003 as it's the most developed and supports more games.

having same problem with libretro/retroarch, if i could just get keyboard control, i'd be ok. Noticed if you turn off the ps4 controller (hold ps button for 10 seconds) keyboard control works again...

Unity,
I was in a similar situation as you, but got the DS4 successfully paired today! My last install was only 1 week old, so not sure where it went wrong, but today I performed a fresh install and got it going!

My steps for successful DS4 pairing:

• Flash retropie 4.0.2.
• Sudo apt-get update
• sudo apt-get upgrade
• retropie setup script, update all installed packages (repetitive?)
• From GUI, Bluetooth pair DS4(#2) using wired DS4(#1). (No freezing while "searching" this time!)
• Configure input GUI, hold down a button on the bluetooth'd DS4(#2) and configure inputs
• Shutdown system
• Unplug wired DS4
• Power up
• Turn on DS4(#2), sync'd right up as player 1, hotkeys and all input working

It must have been a config file issue that was preventing the sync before, because I had performed all of the upgrades on my prior SD card, but this time around it worked wondefully! I have not attempted to sync 2 DS4s at the same time, yet.

P.S. I did zero of the 'extra setup' shown on the github for DS4 controllers. The native packages work for me now. I hope this helps you!

Good luck!

@DanC_1987 You need to install the ds4drv ps4 driver still.

https://pypi.python.org/pypi/ds4drv

Problem is.. without the driver, it says 1 gamepad detected.. but can't be configured. With the driver, 2 gamepads detected.. it configures in the "main menu" setup, and can then navigate through emulationstation... but then it's unresponsive in games.. "controller not configured" message after starting any game.

I've read that updating all binaries and scripts should fix it, but it didn't. I still have a controller that navigates through emulationstation, but completely unresponsive in games. Seriously frustrating.

Hi,

So I ran the commands from SSH. Booted up the Pi and only one controller recognised. I typed in LSUSB and could see that the Pi could only see one controller. After multiple tests I did some testing and it looks like the USB cable is faulty. This would explain why the second controller is not recognised however it did work up until (and after the problems).

I will borrow a controller from a friend and see if I can get this working but to be honest I might just try and get a second controller running with Bluetooth.

Any luck with dualshock 4 controller?

I had no issues setting it up over bluetooth, but the latency is horrible. It's definitely related to the controller not the game, as my ancient logictech wireless (usb dongle) controller has no noticeable lag.
