P2 Controls stopped being recognised. Ultimarc UIO

Hi

I have Rpi4 with RetroPie 4.8, Ulimarc UlimateIO control board. All was working 100%, but I have done something and now P2 Controls not being recognised.
In any core they have stopped working, so MAME, N64, anything... not recognised.
I have tested the cabling with a meter and its all 100% good. I have plugged the controller into a keyboard tester on my PC, all working 100%
I have checked in WinIPAC and the MAME default definitions are still there - all good.
If I re-configure the P2 controls as P1 in the ES GUI it works but now the old P1 (now P2) controls are not recognised.

In summary, everything I have tested says the controller hardware and config are good and working. Its just P2 is not being recognised.

What have I broke?!

I did edit

/opt/retropie/configs/all/retroarch.cfg

To move the exit key from "num1" to "tab" before this started happening but how can this now block P2 being recognised?
But it makes sense that this is at fault because this is the core definition that all other control configs use.

What have I broke?!

Any help, pointers would be massively appreciated.

I found a fix but I am not sure its the answer.

I manually edited /opt/retroarch/configs/allretroarch.cfg
and mapped player2 joystick and buttons to the correct keystrokes as per
https://retropie.org.uk/docs/Keyboard-Controllers/

Because all player2 settings were configured to "nul"
This is now working.
I thought, perhaps incorrectly, the ES automatically mapped P2 controls to a default?

Very curious

ES doesn't configure the P2 controls, when your input is a keyboard it will only configure the controls for P1. For P2, you have to configure them in retroarch.cfg, as explained in the docs.

@mitu Thanks for the info. The thing was it was working without me ever needed to manually configure the P2 Keyboard definitions.
I did "something" then it stopped working and after investigation found all the "nul" entries in retroarch.cfg.

I've been using retroarch for a few years now and have never had to edit the P2 controls.

So something must have changed...

If you're using a gamepad, then you don't have to.
