Cant save specific emulator core for rom.

[qanba]

Hi, cant select in runcomand menu a specific emulator for a rom dont save it or make it efective, but i can change global emulator success, happens with all emulators and roms systems.

Mi setup:

raspi 3
retropie 4.2

The only thing strange i do is Activate root account for be able to edit folders in Winscp.

Screen of message when i try to select specific emulator for rom:

PD: i dont have emulator.cfg file in that folder, if someone send me and i put probably fix it? i dont know why happens... thanks a lot

@qanba perform this command and then try again:

sudo chown -R pi:pi /opt/retropie/configs/
