[SOLVED] Dualshock PS4 controller does not work on MAME

[francegue]

Hello everyone!

I have just installed from scratch on a new sd card the RetroPie v4.3 for a PI2.
I have a wired dualshock PS4 controller (connected via usb) which I configured just fine on emulationstation and it is working good there.
I uploaded one game rom for MAME and when I launch the game I simply cannot do anything, all the buttons I press are not recognised (even if I don't have any explicit error when launching the game). I have to reboot the PI to exit the game.

Under the folder /opt/retropie/configs/all/retroarch-joypads I have the cfg file which has been created by emulation station.
I also uncommented and configured as below the following property in the file /opt/retropie/configs/all/retroarch.cfg :
joypad_autoconfig_dir = "/opt/retropie/configs/all/retroarch-joypads/"

What am I missing?

Thanks,
Francesca

why?

it is applicable. we need to know the game you are playing.

Emulator: (Name of emulator - if applicable) : MAME

there are 9 mame emulators available :) we need to know which one you are using.

[Fra] I read on some posts on internet that it could be a solution. I saw the property was commented, so I tried to uncomment it and fill it with the path of the joypad configuration but it didn't help.

[Fra] Ok, I have just loaded the game called "1942", just one to try before loading the rest. In a previous installation I also loaded other games, but no one was working.

Emulator: (Name of emulator - if applicable) : MAME

[Fra] Ok, sorry :) I am using "mame4all" .

Let me know if you need any other info.

Thanks a lot!

@francegue mame4all isn't a libretro emulator so retroarch.cfg changes would have no effect - i suggest you revert that change.

https://retropie.org.uk/docs/MAME/#mame4all-pi explains configuring mame4all controls, however if you're using a pi2, you should be using lr-mame2003, which IS libretro and should be all working, as far as controls go. however you will need the appropriate romset - see https://retropie.org.uk/docs/Arcade/

@dankcushions : Thanks! I did everything you suggested and my dualshock PS4 controller is working fine now!
Thanks a lot, you made my day! :)

But I have another question now, if I may :) I tried to connect a second controller, wired via usb. It is a PS4 "pro" controller, the one of the newest PS4. It is working fine on emulationstation, even if the other one is connected, so I can use both on emulationstation but it does not work in the games.
I tried with 2 emulators, the mame one (lr-mame2003) and the snes.
I noticed that I have 2 configuration files, but the second one is .bak :
pi@retropie:/opt/retropie/configs/all/retroarch-joypads $ ls -l
total 8
-rw-r--r-- 1 pi pi 887 Sep 24 19:08 Sony Computer Entertainment Wireless Controller.cfg
-rw-r--r-- 1 pi pi 852 Sep 24 14:40 Sony Interactive Entertainment Wireless Controller.cfg.bak

Do you know if there is any additional configuration to do?

Thanks,
Francesca

@francegue great! i'm not sure about your ps4 question, though. i think the problem may be that both controllers identify as the same thing, but have different configurations. that's only a guess, though. maybe you should ask in a new thread?

[francegue]

@dankcushions . ok, I'll open a new thread. Thanks!
