runcommand.log retains "%ROM"

[beppi]

Good day all.
I was trying to add to my retropie the Coleco system.
I receive this error when runcommand tries to run a rom:

Executing: /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-bluemsx/bluemsx_libretro.so --config /opt/retropie/configs/coleco/retroarch.cfg "%ROM%" --appendconfig /dev/shm/retroarch.cfg

It seems that it cannot substitute the %ROM placemark with the correct rom name.

es_systems looks like this, the rom directory is correct, the extension is correct.

  <system>
        <name>coleco</name>
        <fullname>ColecoVision (1982)</fullname>
        <path>/home/pi/RetroPie/roms/coleco</path>
        <extension>.col .COL</extension>
        <command>/opt/retropie/supplementary/runcommand/runcommand.sh 0 _SYS_ coleco %ROM%</command>
        <platform>coleco</platform>
        <theme>coleco</theme>
  </system>

Probably there is a configuration file I missed to configure, but I cannot find which one.
Also, there is a little misunderstanding between "coleco" and "colecovision", but I tried to make them all uniform and set everything to "coleco".

Any idea?
Thank you.

Nevermind, closed ticket, I mistyped one command, sorry. I cannot delete the question.
