Please add more info about your setup, as detailed in https://retropie.org.uk/forum/topic/3/read-this-first.
Use the Android mode to pair the controller and do the configuration in EmulationStation in this mode. What games/emulators are not working with the gamepad ? Did you install other drivers from RetroPie-Setup ?
The quickest way I have found to setup 5200 controls in RetroPi is
open a 5200 game then enter the retro arch quick menu.
From there you want to go down to options. Then set the Atari System to 5200. After that go back to the quick menu.
Now select controls.
Go down to Port 1 Controls and click it.
Change Device Type from RetroPad to Atari Joystick.
Back out to the controls menu.
From the Controls menu Save Core Remap File.
Go back to the Quick Menu.
Back out to the main menu.
Open Configuration File and Save Current Configuration.
Back out to the Main Menu and Quit RetroArch.
Now your controller should work with 5200 games
