@realazyria read the fullscrape post, or ask paradadf for the fastscrape version

Bonsoir ! J'ai réglé mon problème en ré-installant toute une recalbox et en la mettant à jour en 4.1 Unstable et en récupérant un romset complet pour FBA en .39 Maintenant le jeu se lance sans soucis ^^ Merci pour toute l'aide apportée.

Just access your RPI from your PC via network neighborhood and navigate to the \romsfolder. Inside this folder you'll finde the respective system folders. In your case it's \mame and inside this folder, you'll find a \downloaded-images folder.

@tdelios It don't think it wise it would mean that everytime you make a error in your manual scrape your image and gamelist.xml part related to the not found game would be deleted and you would have to do it all over again. Besides as not found games don't appear in EmulationStation and images are so small compared to modern SD cards, USB sticks or HDD it's not really an issue. It's also simpler to do your scrape once you have manually remove every game you didn't want than doing before
