Custom controller for individual cores

I’m using an XBox controller. I’d like to map two specific buttons for the B and A buttons if I’m playing NES. Three different buttons for Sega or TG16. One layout for PS1, etc. Has RA added this feature yet?? Seems like a no-brainer.

I’ve tried searching for an answer, but most questions and answers were from years ago.

Thank you internet friends in advance!!

quick menu > controls. You can move the cores’ functions around on the retropad/gamepad.

Hey Hunterk, I appreciate your quick reply. I didn’t receive any notification you’d responded. I’m currently going through my TurboGrafx games and I cannot seem to get it to work. The buttons seem properly configured, but when I push a button on my XBox controller, nothing happens. Any ideas why? I really appreciate your help.
