PS3 Controller with RA

I need help figuring out how to use my PS3 controller with the ps1 RA core. I’ve used controllers for all and got it to work but I want to be able to map R3 and L3 buttons so that I can play a certain game and controllers for all will not recognize these extra buttons.

I know there’s a way to get RA to recognize my controller without CFA, using btstack, but I can’t figure it out. someone help :confused: I’m using the latest nightly RA
