Re: PSP + FuSa gamepad: your best SNES USB controller for RetroPie

Hi friends of the @administrators group, hello @herb_fargus could you add the python script of this program alongside an option to launch the script at launch to the RetroPie setup? This script as FuSa gamepad lets you use your PSP as a gamepad, but this time wirelessly (wich I woul love to have on my pi) so you could play movies in Kodi with a great device for multimedia
