I did use the theme manager from within BigBox when I updated CoverBox (and for initial installation), but I will delete the folder and reinstall to see if that works.
@faeran No dice after a clean install from within BigBox. My platform names do not match the platform names used by CoverBox, so I have to change image folder names and "TextGameView" XAML files so they match my set up. Is it possible the correct fonts are being applied from some other file that is using a default platform name?
A while back I found a set of platform clear logos with device images. I really like using them on the platform wheel for a CoverBox/Retrotastic theme.
