The content of your theme files must follow a certain script. Each object must be placed within the <view></view> tags.
<view>Interface screens are managed via so-called views. These views can have several attributes.
nameThe name attribute is used to indicate on which screen its content should act. It can have one of these values at the same time:
system: corresponds to the list of systems.setailed: corresponds to the list of games.menu: corresponds to the options menus.gameclip: corresponds to the “game clips” screen saver.This attribute can have one or more values at the same time:
<view name=“system”>
...
</view>
<view name=“system, detailed”>
...
</view>
Using multiple values means you're using the same data in the <view> tag in different places (in the second example above, in the system view and the game list view).
