@dogeymon If you don't know how to edit a text file I'm sorry I don't have time to teach you. Try googling it or searching here. It's been explained many many many times.
I would suggest you delete the es_systems.cfg file in /home/pi/.emulationstation/and just use the default where systems automatically get added.
Someone has created a custom config file, If it wasn't you, who was it?

yes. /etc/emulationstation/es_systems.cfg is managed automatically when adding / removing packages.

@Sevik said in ScummVM Game won't launch from RetroPie:

I too have the same problem.
Quite sure it is a permission problem as the log says:
····/opt/retropie/supplementary/runcommand/runcommand.sh: line 827: /home/pi/RetroPie/roms/scummvm/+Start ScummVM.sh: Permission denied

You were right.. It Is a permission issue .
So I took a look at my fstab one more time and edited it.
This is my new command:

UUID=E44B-FC4E /home/pi/RetroPie vfat auto,users,rw,exec,uid=pi,gid=pi 0 0

I don't know if this change is affecting other permission issues, but it seems to work.

I found the command in this RetroPie topic.

@mediamogul said in [Solved] Cannot configure DOSbox and ScummVM:

OK, drop to the command line (f4 key), then type "sudo nano /etc/fstab". After that you can add the line "/dev/sda1 /media/usb0 vfat auto,users,rw,exec,uid=pi,gid=pi 0 0". Then hit "ctrl+o" to save, "Enter" to confirm, "ctrl+x" to exit and finish it off with "sudo reboot". That should do it, but we'll see.

Just made sure my RPI was up to date with latest scummvm binary and the opengl option worked ok here. Perhaps something else in your config - you could remove /opt/retropie/configs/scummvm and re-install from binary and see if that helps.
