Atari joystick and emulator downloads in Lakka on Raspberry Pi 3

I can’t seem to get the Atari joystick or understand updating the emulators on my raspberry pi 3. I am using 2.1 of the software on Raspberry Pi 3.

I can’t find the directory to download the emulators from the directory that was originally under. I have the emulators but I just don’t know where they are or if they get updated automatically.

The joystick when I just boot it up with that (Stelladaptor 2) it does not recognize that under the user bindings. I have a keyboard connected and that shouldn’t be a problem. It takes me up to a screen where I have to type something in for some reason. The keyboard does not work with the screen. Other controllers work with no problems but I have an itch to play Atari 2600 games and want to do it with the original controllers.

Help me out,

Thanks.

Can you provide the output of lsusb ?

Thank you.
