====== Scrape From ======

This option is to allow you to change the source of where your images are coming from. It allows you to choose from [[http://adb.arcadeitalia.net/|Arcade Database]], [[https://thegamesdb.net/|theGameDB]], [[https://www.screenscraper.fr|Screenscraper]] and [[https://www.igdb.com/|IGDB]].

Screenscraper offers more options for game scraping (for example several image options, you can scrape video previews, etc.). But there is also a **limitation in the number of assets you can download each day**: 50,000 requests max per day. Also, if you use a "mix" for the image, be aware that you need to download a screenshot + box + game title/marquee, which are 3 downloads for 1 composite image. 

In order to use ScreenScraper, you need to create a login on [[https://screenscraper.fr/|their website]] (otherwise you'll get a message in French telling that you need to register an account there).

Configuration is through **Main Menu** > **Scrape**. More info at [[:menu_tree#scrape]].

IGDB has been introduced with Batocera 42, and it requires to enter IGDB ''Client ID'' and ''Client secret'' on scraper menu. You need to follow [[https://api-docs.igdb.com/#getting-started|their API guide]] to get your own. As of now, you need a Twitch account to access IGDB API. The ''Client ID'' and ''Client secret'' are pretty long strings, so you might want to copy/paste them into a file, see how to proceed below.

===== F.A.Q. =====

==== Is there any way you can launch scraping from the command line, like other retrogaming distributions? ====

No, scraping is part of the EmulationStation binary, and can be only started from there. However, you can use [[https://forum.batocera.org/d/1288-arrm-scraper-gamelist-roms-manager|the ARRM tool]] to easily manage your ''gamelist.xml'' files from Windows.

==== I have a very complicated login or password, where can I copy/paste it rather than using the EmulationStation keyboard? ====

You can edit ''/userdata/system/configs/emulationstation/es_settings.cfg'' and edit the section:

For Screenscraper:
<code>
    <string name="ScreenScraperUser" value="your_login" />
    <string name="ScreenScraperPass" value="your_pass" />
</code>

For IGDB:
<code>
    <string name="IGDBClientID" value="your_id" />
    <string name="IGDBSecret" value="your_secret" />
</code>

Make sure EmulationStation is stopped before editing this file, otherwise **ES will reverse your modifications**. If you're not sure how to stop EmulationStation before editing this, you probably should use the UI to enter your credentials ;-)

==== I've entered my username and password correctly, and triple checked, yet I still can't login! ====

If your username/password contains any special characters (like ''?'', ''Ó'', ''±'', or ''№'') it won't be parsed correctly by ES and you'll fail to login. Should have chosen a simpler password! :-P

Just kidding. You must escape special characters with a preceding backslash (''\''), eg. ''%%specialcharacter?inmypassword%%'' would become ''%%specialcharacter\?inmypassword%%''. If the ''\'' itself is in your password, just use ''%%\\%%''.
