i have installed a multiple Operating Systems ( LibreElec 9.X and Recallbox) with Noobs on RPi4.
i would change my es_systems.cfg in emulation station because i like to change some modules.
the problem: i cant find any es_system.cfg 
where is the es_system.cfg?
if i put a new one in share/systems/.emulationstation/ there is no change at recallbox.....deleted every module to test but there are all modules.....
