I’ve been trying to get mod Lucida Blackletter into the game. Unlike in HD, fonts are not listed in the key-value-strings-utf8.txt
What I have found so far is two folder locations:
You can get Lucida Blackletter (or any other font) in the main menu by deleting all the fonts in AoE2DE\resources_common\wpfg\fonts and putting in a font of your choice. It will also appear on the loading screen for matches.
Unfortunately, making a mod that replaces every font file in that folder doesn’t seem to work. I think I recall hearing somewhere that wpfg mods don’t work. Perhaps because those files are loaded before mods. So you have to do it manually for now.
Still though, it is a partial success:
The question remains of how to mod the remaining fonts. Within AoE2DE\resources_common\fonts there are several massive combined files with matching .txt .png .DDS .box files. I think these control most of the remaining ingame fonts. Unfortunately, I’m not sure what to do with them - they are font asset files, but I have no experience dealing with those.
Delete them and the game refuses to launch.
So that’s where I am so far.
