Can the fonts be changed?

[Your Computer]

Effects voice text is another form of subtitle text. Unless the font size is shared, that wouldn't change journal font sizes. Effect voice text isn't the only text that you can change font sizes for in the menu.cfg file. For my own mods i haven't taken time to adjust every aspect of the menu.cfg file, but from what i have messed around with i know that some things are indeed shared. Of course, this is not to say that you'll achieve what you want.
