Use raspi-config and configure the system to auto-login to the console. If EmulationStation doesn't start automatically after a reboot, then use the setup script to enable the autostart of EmulationStation - see https://retropie.org.uk/docs/FAQ/#how-do-i-boot-to-the-desktop-or-kodi.

Is there any reason you're not using the RetroPie image directly ?

@mitu Thats where i looked, its gone-vanished of the face of the earth, hope the setup script fixes it

@mitu I made it! I have deleted whole scummvm folder, rebooted and the ES finallt works!

Thank you everyone. The problem is officially solved.
