RetroArch is a free and open-source software emulator and frontend that can run a wide variety of video game consoles and computer systems. It is available for a variety of platforms, including Windows, macOS, Linux, Android, and iOS. One of the features of RetroArch is the ability to add thumbnails to games, which can help to make it easier to identify and select games from the list. Adding thumbnails to RetroArch is a relatively simple process, and it can be done in a few different ways.
There are a few different ways to add thumbnails to RetroArch. One way is to use the built-in thumbnail scraper. This scraper will automatically search for and download thumbnails for games that are in your RetroArch library. To use the built-in thumbnail scraper, open RetroArch and go to the Settings menu. Then, select the “Scraper” tab and enable the “Automatic Thumbnail Download” option. The scraper will then automatically download thumbnails for any games that are missing them.
