@jamesnj ...just getting back around to the forum.

Hmm, not sure why the override files in /opt/retropie/configs/atari5200 aren't working. They should be the last ones loaded.

Strange.............you could try looking at the runtime log in /dev/shm and see what Retroarch is loading (and in what order). If I remember right, the file is: runcommand.log

@jimmyfromthebay ,

They are different sizes:

pi@retropie:~/RetroPie/roms/atari5200 $ ls -lhart *Dig* -rw-r--r-- 1 pi pi 16K Jul 13 21:52 'Dig Dug (1983) (Atari).a52' -rw-r--r-- 1 pi pi 17K Jul 13 21:53 'Dig Dug c (1983) (Atari).a52'

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.

you may want to set the Device Type to Atari Joystick for
Port 2 controls if you're playing 2 player games.

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

I found out that the problem is caused by shader I applied to all liberto emulators,
I guess Atari800 emulator doesn't like shaders.
Disabled it for this specific emu and it's working now!
Thank you mitu for answer.

@mahalingam it was fixed, so if you're getting the issue open a new topic with some info.

@mth75 Yeah i managed to figure it out, my configs/all/retroarch.cfg global override was doing something, so i deleted retroarch.cfg in config/atari5200/ and it reset it and save directory override and all good got sound now

@LS650 its nice to see more and more atariage users showing up on here. Im pimpaul69 on atariage.
