Larger fonts for XBMC in Raspbian

Edit the file /usr/share/xbmc/addons/skin.confluence/720p/Font.xml and add the following code inside the <fonts> block:

    <fontset id="Massive" idloc="31393" unicode="true"> 
    <!-- Normal Fonts -->
        <font>

    <!-- Title Fonts -->
        <font>

        <font>
            <name>WeatherTemp</name>
            <filename>Roboto-Bold.ttf</filename>
            <size>80</size>
        </font>
    </fontset>

To select the newly created fontset go to “System > Settings > Appearance > Skin > Fonts” and change it to the blank value.

If you edit the file /usr/share/xbmc/addons/skin.confluence/720p/language/English/strings.po (or the corresponding file to your current language) and add the following code at the end it should appear “Massive” and not a blank text in the fonts option but that didn’t work for me though:

msgctxt "#31911"
msgid "Massive"
msgstr ""
