If set to `ascending` then items will be rendered progressively higher from left to right or from top to bottom depending on the carousel orientation. If set to `descending` the opposite takes place with items being progressively rendered lower from left to right or top to bottom depending on the carousel orientation. Finally `ascendingRaised` and `descendingRaised` work identically to `ascending` and `descending` with the only difference that the currently selected item will be raised above the other items.

 * `itemRotationOrigin` - type: NORMALIZED_PAIR
     - Point around which the items will be rotated. The X axis of this property is the distance from the left side of the item to the center of the wheel in multiples of the size defined by the `itemSize` X axis. So if for instance the itemSize X axis is set to 0.2 and itemRotationOrigin is set to -2, then the center of the wheel will be at a -0.4 distance from the left side of the item. In other words, if specifying a negative number the item will be located on the right side of the carousel, i.e. the wheel will be to the left and if specifying a positive number the wheel will be to the right. Note again that this is calculated from the left side of the item, so to get an identically sized wheel as the -2 wheel just mentioned you need to define 3 as the value rather than 2 if you want the wheel to the right side of the item. This is not an error but due to the way that coordinates are calculated. The Y axis should normally be left at `0.5` or you may get some weird results. It is however possible to use this axis value creatively if you know what you are doing.

 Multiple languages are supported by ScreenScraper, and this affects translations of game genres and game descriptions. As the option name implies this is the preferred language only as not all games have had their metadata translated. Unfortunately some less used languages have quite few games translated, but hopefully this will improve over time as there's an ongoing community effort to make more translations. If the preferred language is not available for a game, ES-DE will fall back to using the English metadata.

Even with this option disabled, metadata entries which are set to their default values will be populated by the scraper. In other words, this option only affects overwriting of previously scraped data, or data manually entered via the metadata editor. Game names are considered as set to their default values if either corresponding to the physical game file on disk minus the extension (e.g. the entry _Commando_ if the file is named _Commando.zip_), or for arcade games if corresponding to the MAME names as defined in the bundled mamenames.xml.

 When a certain game media file does not exist for the selected region, ES-DE automatically performs a fallback to the regions _world_, _USA_, _Japan_, _EU_, and _custom_ in this specific order. If this setting is enabled then an additional fallback is performed to all other country-specific regions. This makes it possible to scrape media for some games only released in specific countries like Brazil or South Korea. It may also make it possible to scrape some game media that have been uploaded to ScreenScraper using the wrong region. The special _ss/ScreenScraper_ region is also enabled via this option, and among other things it contains media for games that never had official releases. This is relevant for instance for OpenBOR and PICO-8 games where 3D boxes and other images may become available. The drawback of this setting is that you may get inaccurate data such as box art in the wrong language or unofficial box art for arcade games, so you may want to experiment with this option on a per-system basis.

It's normally resolved within a few days, but in the meanwhile activating this setting will have the scraper automatically make up to eight additional attempts when this error occurs. That is normally enough to complete the search, but if not, just press _Retry_ in the error dialog and ES-DE will try eight more times. This setting applies to both the single-game scraper and the multi-scraper. The following error notification dialog and corresponding es_log.txt entry is displayed when this error occurs: "Error downloading thumbnail: SSL peer certificate or SSH remote key was not OK".

If a value is set here for a display that does not actually exist, then ES-DE will set it to 1 upon startup. Index 1 is the primary display for the computer. It's also possible to override the setting by passing the --display command line argument. Doing so will also overwrite the display index setting in es_settings.xml.
