Unable to connect my PS3 controller to RetroArch! Help Please!

I just downloaded it today adn am trying to connect mmy ps3 dual shock 3 controller via usb, i havent found much anywhere on how to get it to work, when i plug it in it says on the bottom “1356/616 not configured” its the only usb controller i have if anyone can help me figure it out i would be really grateful.

You need to use an xinput wrapper and then it will be automatically configured when you plug it in.

Not sure if there is a better one, but I remember people use to use DS3Tool to rig up their Dual Shock 3’s on PC. For my Dual Shock 4, I use DS4Windows.
