Emulator: none
How to replicate the problem:
So .. The 2 joystick are connected perfectly and I can test them with JSTEST
The buttons are NOT the same and are a little messed up between the two joys but I think that this is not a big problem.

so to reproduce I simply start the configuration procedure and a file is created (as you can see above)
if I start to configure the second joystick the first file is overwritten by the second one.. The second joystick is correctly configured now but the FIRST one results messed up..
The question is , why emulationstation is considering the 2 joystick as one and is not creating two different configurations ??
Thank you

(Can someone help me via discord also ? Thank you)

This is actually the problem - if they're wired differently, then they'll produce different configurations. EmulationStation, just like the majority of emulators, use the name reported by the joypad to identify the configuration. If you have 2 gamepads with the same name, but different inputs, they'll not work correctly since they'll not be able to share the same configuration.
