Running ScummVM games on RetroArch

What am I doing wrong? Please, need help.
My example Day of the Tentacle:

  • Game is in /home/cpi/games/SCUMMVM/Day of the Tentacle/
  • .scummvm is in /home/cpi/games/SCUMMVM/Day of the Tentacle/Day of the Tentacle.scummvm (text inside is “tentacle”)
  • .sh is in /home/cpi/launcher/Menu/GameShell/22_SCUMMVM/Tentacle.sh (inside “retroarch -L /home/cpi/apps/emulators/scummvm_libretro.so /home/cpi/games/SCUMMVM/Day of the Tentacle/Day of the Tentacle.scummvm”)
  • scummvm_libretro.so is in /home/cpi/apps/emulators

Question is why shortcut leads me not to game but to scummvm launcher? Is it how it works? Or I made a mistake?
Thanks in advance!
