how can i install this function? it is somewhat lacking in some Playstation 1 games.
raspberry pi 3 model B.
When in game press Hotkey + B (X on PS3 controller) to enter RetroArch QuickMenu. Then under options you can enable rumble
I didn't have to do anything. I used an adapter to control the original ps2 to usb and the vibrate function worked perfectly.
My LEFA PS3 controller is not vibrating.
Equally thanks for the help and I am happy that everything is working.
