 After ES-DE finds at least one game file, it will populate that game system and the application will start. If there are no game files, an error messsage will be shown, explaining that you need to install your game files into your ROM directory. You will also be given a choice to change the ROM directory if you don't want to use the default path. Please refer to the game installation procedure below in this document for more information regarding this.

 If the theme supports it, there's a gamelist information field displayed in the gamelist view, showing the number of games for the system (total and favorites) as well as a folder icon if a folder has been entered. When applying any filters to the gamelist, the game counter is replaced with the amount of games filtered, as in 'filtered / total games', e.g. '19 / 77'. If there are game entries in the filter result that are marked not to be counted as games, the number of such files will be indicated like 'filtered + filtered non-games / total games', for example '23 + 4 / 77' indicating 23 normal games, 4 non-games out of a total of 77. Due to this approach it's theoretically possible that the combined filtered game amount exceeds the number of counted games in the collection, for instance '69 + 11 / 77'. This is not considered a bug and is so by design. This gamelist information field functionality is specific to EmulationStation Desktop Edition so older themes will not support this.

 There is a help system available throughout the application that provides an overview of the possible actions and buttons that can be used. It's possible to disable the help system for a somewhat cleaner look using a menu option.
