This is a GUI replacement for the in-game national flags display, it's based on a resource pack made by Isaac Chavira and it contains the most used nationalities in the game. The files are in .png 48x48 resolution if you would like to make some yourself.
If you like this mod I strongly recommend installing also this mod to replace the condition and penalty flags.
To install: replace the content in this folder: C:\Program Files (x86)\Steam\steamapps\common\assettocorsa\content\gui\NationFlags
Important: always remember to make a backup of the folder, in case you want to go back to the older flags.
Big shout-out to Isaac for his awesome work!
Here are some examples:
