Controller issue?

[Chortle]

Ive downloaded ppsspp onto my windows 10 notebook and ive even got some games My only trouble is not being able to use a controller. Ive been trying to use a regular ps3 dualshock controller and remapping controls, but that has proven ineffective. The controller is connected and shows up in devices and printers, but all that happens is the 4 flashing lights. How exactly can i fix this?
