+1, I have the same problem. I have a copy of a previous gamelist, where everything works correctly.
but if I add a new game, with the folder name that is, and inside the .scummvm file, it comes to me in the batocera menu and it works, when scraping it, it does not let me launch it.
others like toonstruck, I add the toon.scummvm file, and it does not release it either ....
I'm unable to make everything work correctly
