On clean install on retroarch 1.21.0, I’ve got 2 controllers detected (PS4/XBOX360). I want to set the PS4 always for Port 1 and XBOX for Port 2.
Test with :
Port 1 - PS4 - Reservation Type = Prefered
Port 2 - XBOX - Reservation Type = Prefered
Restart Retroarch :
Now Port 1 is XBOX - Prefered and Port 2 is PS4. Preferred 
Test with : Port 1 - PS4 - Reservation Type = Reserved - Reserved Device for this player : PS4 [CRASH] So I cannot test this settings. It crashed every time I try to set this “reserved device settings”.
How it is possible to set the correct device for each player everytime ? Thanks
