Swap x and y in ES?

[quicksilver]

Is there a way to swap x and y in just emulation station? I have done it for a and b but would like to swap x and y too.

I would love to see this added to the setup script as well. When using XBOX pads the official configuration leaves the X & Y buttons swapped when using favorites and random game select.

You can reconfigure the RetroArch button mapping so emulation station sees it correctly. And keep the game cores correct.

Myself I just map the controllers through the emulation station prompt “correctly” with the proper button configuration so A is A and so on. And then change each core so the buttons map correctly per system. That’s quite a process but once the configs are done you can just drag and drop from a backup obviously.

I know this post if fairly old but here is how to swap a/b & x/y together. Replace the contents of the file: /opt/retropie/supplementary/emulationstation/scrips/configscripts/emulationstation.sh with the code below. Then enable the swap a_b option as normal. Finally reconfigure you gamepad.

If you want to know how it works so you can customize it further (i.e. maybe swap only x/y, or swap some other buttons) this is a brief explanation. When you turn the swap a_b option on it changes the value of "es_swap_a_b" from 0 to 1 in /opt/retropie/configs/all/autoconf.cfg. Then the script below checks if that value is 0 or 1 for a, b, x, and y (the original checks only for a and b). If the value is 0 it leaves them as is. If the value is 1 it assigns the other value per the definition in the script below. I am not an expert programmer otherwise I would try to add it as a separate option in the retropie configuration tool and have it write a separate variable for x and y swap. In any event this works well for me using Xbox controllers.

Thanks mate, I was always annoyed by this!
