I have a raspberry pi 3 B using batocera in a sandisk class 10, I need to make modifications to the system to be able to use my joystick (ipega 9067) without modifying the file /etc/udev/rules.d/99-joysticks -exotics .rules I can not use it and configure it and also need to modify the system to put my collections of games, okay I can change all that, but when I restart the raspberry pi 3 loses all the modifications I made, could anyone help me?
