Thanks for your help!

And what is required to do this?
The es_systems.cfg changed like above and the game in roms folder in mam4all-pi or just Standard config after RetroPie has installed and the rom in standard rom folder?

EDIT: Changed the es_systems.cfg, copied a rom in the self created roms folder in mame4all-pi and rebooted. When I now try to start it’s saying “mame: command not found”.

What’s wrong?
