how to multiplayer with DS4 controllers? only one works at a time

[shielduser0193]

Hi all, I'm new to Dolphin and I've gotten it working on my nVidia Shield Android TV with a few games. I use PS4 DS4 bluetooth controllers, and multiple controllers work fine with native Android games, but in Dolphin I can't figure out how to get a second controller recognized. Pressing buttons on it does not take over control of P1 or enter as P2, only the "B" button works bringing up the menu from the side. Any clues for me?

Android TV 8.2
Dolphin 5.0-12716

Did you set up the second controller in Dolphin's controller settings?

It probably is something that simple! 
But I've scoured the menus and I can't find this setting.  I've seen some screenshots of others and the PC Dolphin interface seems pretty significantly different than what I'm seeing on Android.  If you could point me to the setting, that would be great!

I should add, if I go to, for instance, Wii Remote, I turn Remote 1 to Emulated, everything works great single player. Then I go back there and turn Remote 2 to Emulated... now one remote is controlling two players, every input duplicated for both.

That is essentially what I was wondering if you had done. If you were using the second controller when setting up the different buttons and such for Wii Remote 2, then I believe there's some sort of problem where Dolphin can't distinguish between your two controllers, and I'm not aware of anything that you can do about it other than using two controllers of different models/brands. It's possible that a larger change to Dolphin's input handling system could fix this, which is something I would like to do but have no hope of being able to finish soon.

Thank you for the response!  Mupen64FZ recognizes these controllers separately and gives them different numbers, but I understand that may be difficult and/or low priority.  Thank you again for your time.
