Scraping

ES-DE supports the two scraper services ScreenScraper.fr and TheGamesDB.net.

Scraping allows you to make the games look "pretty" with coverarts, icons, discimages and more. Read up on the ES-DE userguide on scraping here:

###Quick tips

On most occasions you want to use ScreenScraper and not TheGamesDB. But for PC titles scraping from TheGamesDB might be better.
You will need to register an account on ScreenScraper.fr to scrape (support them on Patreon for faster downloads, more scrapes per day and priority scraping).
Login to your Screenscraper.fr account inside of the ES-DE interface in RetroDECK
Choose what content you want to scrape (remember that each content you choose could take up several mb of data per game).
Do an initial scrape of all the games you want to scrape.
If some games are missed do a more narrow scraping by enabling Scraper -> Other Settings -> Interactive Mode -> On& Scraper -> Other Settings -> Auto-Accept Single Game Matches -> On and choose to scrape by games missing metadata. This will allow you to select each game from a list and also tweak the searches of the missing games.
In some cases you need to remove certain aspects of the name like if a rom comes both with a Japanese name and English name, you could try to remove one of the names to find a better result.
