[Mutax]

Hello guys, i'm a computer nooby and i really need some help. i followed the instructions on "How to Easily Connect a PS4 Controller to PC", a video on youtube; and after I followed all the instructions, i still can't figure out how i'm suppose to map the buttons on the Ppsspp games. I'm using Zadig and it's not working on my Ppsspp emulator. Am i supposed to map buttons? I'm not quite sure what to do after i download the wireless controller on the driver. Please help i'm totally confused.
