Themes
EmulationStation allows each system to have its own "theme." A theme is a collection of display settings and images defined in an XML document.
ES will check two places for a theme: first, the system's search directory for theme.xml. Then, if that's not found, $HOME/.emulationstation/es_theme.xml.
Almost all positions, dimensions, etc. work in percentages - that is, they are a decimal between 0 and 1, representing the percentage of the screen on that axis to use. This ensures that themes look similar at every resolution.
Example
Here's a simple theme that defines some colors and displays a background:
<theme>
<listPrimaryColor>0000FF</listPrimaryColor>
<listSecondaryColor>00FF00</listSecondaryColor>
<component>
<type>image</type>
<path>./theme/background.png</path>
<pos>0 0</pos>
<dim>1 1</dim>
<origin>0 0</origin>
</component>
</theme>
All themes must be enclosed in a <theme> tag.
Components
A theme is made up of components, which have various types. At the moment, the only type is image. Components are rendered in the order they are defined - that means you'll want to define the background first, a header image second, etc.
The "image" component
Used to display an image.
<path> - path to the image file. Most common file types are supported, and . and ~ are properly expanded.
<pos> - the position, as two screen percentages, at which to display the image.
<dim> - the dimensions, as two screen percentages, that the image will be resized to. Make one axis 0 to keep the aspect ratio.
<origin> - the point on the image that <pos> defines, as an image percentage. "0.5 0.5", the center of the image, by default.
<tiled /> - if present, the image is tiled instead of resized.
Display tags
Display tags must be at the root of the tree - for example, they can't be inside a component tag. They are not required.
<listPrimaryColor> - the hex font color to use for games on the GuiGameList.
<listSecondaryColor> - the hex font color to use for folders on the GuiGameList.
<descColor> - the hex font color to use for the description on the GuiGameList.
<listSelectorColor> - the hex color to use for the "selector bar" on the GuiGameList.
<listSelectedColor> - the hex color to use for selected text on the GuiGameList. Default is -1, which will not change the color.
<listLeftAlign /> - if present, the games list names will be left aligned to the value of <listOffsetX> (default 0.5).
<hideHeader /> - if present, the system name header won't be displayed (useful for replacing it with an image).
<hideDividers /> - if present, the divider between games on the detailed GuiGameList won't be displayed.
<listOffsetX> - the percentage to offset the list by. Default is 0.5 (half the screen). Will also move the selector bar.
<listTextOffsetX> - the percentage to offset the text in the list by. Default is 0.005. Only works in combination with <listLeftAlign />.
<gameImageOffsetY> - the percentage to offset the displayed game image by. Default is the height of the header font.
The Fast Select box can be themed with these tags:
<fastSelectColor> - the hex color to use for the letter display on the Fast Select box.
<boxBackground> - path to a background image file. ~ and . are expanded.
<boxBackgroundTiled /> - if present, the background will be tiled instead of stretched.
<boxHorizontal> - path to the "left" border image file. It will be flipped for the right border. ~ and . are expanded.
<boxHorizontalTiled /> - if present, the horizontal image will be tiled instead of stretched downwards.
<boxVertical> - path to the "top" border image file. It will be flipped for the bottom border. ~ and . are expanded.
<boxVerticalTiled /> - if present, the vertical image will be tiled instead of stretched to the right.
<boxCorner> - path to the "top left corner" image file. It will be flipped for the top right, bottom right, and bottom left corners. ~ and . are expanded.
Audio
Themes can also define menu sounds. Sounds should be in the .wav format.
<menuScrollSound> - path to the sound to play when the game list is scrolling.
List of variables
Variables can be used in position and dimension definitions. They can be added, subtracted, multiplied, and divided. Parenthesis are valid. They are a percentage of the screen.
$headerHeight - height of the system name header.
$infoWidth - where the center of the horizontal divider is drawn.
