Error launching Amiga Games in Attract Mode - No config found for system uae4all

[superdan]

Hi all,
when i launch any amiga game via attract mode i have this message:

No config found for system uae4all

What' am i missing?

I have installed uae4all without any error and also ive created .uae config files in rom folder for each game via https://github.com/Douggernaut/RetroPieAssistant/tree/master/Amiga

In emulationstation it works ( it opens uae4all screen ).
Thanks for your replyes
