|Version||0.204||Fixed in Version||Build||64-bit|
|Summary||07200: Stable Controller IDs for 2 controllers of the same brand.|
The Stable Controller IDs configuration ( https://docs.mamedev.org/advanced/devicemap.html ) is not working using 2 controllers of the same brand.
This configuration is based on the device ID, but if the controllers that have generic names like "PS4Controller" MAME can not disambiguate between these devices.
<mapdevice device="PS4Controller" controller="JOYCODE_1" />
<mapdevice device="PS4Controller" controller="JOYCODE_2" />
A solution to this problem can be found at this link (reply #12 by tverona)
In his private build he made MAME able to recognise also the "Instance" for each device, so it's possible to write it in the .config file.
<mapdevice device="instance_f1641160-a808-11e5-8006-444553540000" controller="JOYCODE_1" />
<mapdevice device="instance_f1641160-a808-11e5-8002-444553540000" controller="JOYCODE_2" />

To my knowledge, such information can be added to the mapdevice entry already:
The documents, I fear, are not set up to handle the duplicate controller ID scenario, but it should work.

@Tafoid Yes but this is just for Directinput, so it will work only on Windows. Right?
Is there a way to ask MAME to visualise the instance on MacOs an try adding it to the mapdevice?
Also SDL2 should support InstanceID:

|MacOS doesn't let you see the IDs of the controllers at that level of detail. I added the ability to use the SDL2 JoystickInstanceID but it's just a generated number on non-Windows systems. If the stable controller feature is important to you, you need to use Windows, unfortunately.|
