If you edit the gamelist.xml, follow Hhromic's post to change the game path to end with the folder.
Or change the folder name to remove the pseudo extension ".svm" but this is kind of a loss of a working organization function.
roms via samba network
\\roms\scummvm\gamelist.xml
roms via root directory
/home/pi/RetroPie/roms/scummvm/gamelist.xml
alternate folder that gamelist.xml can be generated at with skyscraper
/etc/emulationstation/~gamelists(???), or maybe
/opt/retropie/configs/all/emulationstation/gamelists/?
