Hardware: INTEL 12th gen mobile + NVIDIA 3050 RTX + XBOX One S controller + dualshock 4 (both connected BT)

Description of the Issue Using flycast 2.2 public build. When using individually each controllers, they work fine and i can control all games without issues. Same happens when using 2 XBOX controllers. However, as soon as the dualshock is introduced in combination with one or both XBOX controllers, no inputs work anymore and the screen displays wrong controller names:

Case of 2 XBOX + 1 DS4:

Case of 1 XBOX and 1 DS1:

Working cases with only the 2 XBOX controllers:

And with only the DS4:

Debugging Steps Tested 1) connected all 3 controllers and noticed that 2 PS4 controllers + 1 XBOX controller appeared Tried to perform mappings for all 3 lines with all 3 physical controllers : none responded

2) close flycast and delet emu.cfg, restart with DS4 shut down Working correctly : both XBOX controllers are assigned to A and B ports and can be configured

3) close flycast and delet emu.cfg, restart with 1 DS4 and 1 XBOX controller PS4 Controller appearing twice, tried to perform mappings for all 2 lines : none responded

4) close flycast and delet emu.cfg, restart with only DS4 connected All working fine

Please try with the latest master build since SDL has been upgraded a few times since v2.2.

Downloaded last master :

Same behaviour:

Not sure the issue is with SDL, as the library supports PS4 controller since multiple versions.

Made an additional test:

With this, i am able to setup controller in port C, and it detects buttons of 2 controllers:

• the DS4 (as SDL)
• one of the 2 XBOX controllers (as dinput)

As you see :

Here i have defined up on the DS4 and down on the XBOX controller

I think the index has issues, as SDL and dinput do not share the same indexes, the joystick instance messes up the devices. 2 devices merged into 1.

The device in port A is not configurable, on any of the controllers.

Here are my device numbers: XBOX dark :

• SDL index 0
• dinput index 0

XBOX white :

• SDL index 1
• dinput index 2

DS4 :

• SDL index 2
• Dinput index 1
