In my 1978/79 patch I've replaced China with Poland, and I'd like to have the Polish flag instead of the Chinese one. I've managed to edit the flags that appear in the 'Select teams', 'Team edit' and the 'Team management' menus, but I can't find the pop-up menus that appear during the game (which also have the teams' flags on it). So, does anyone know how to edit the flags on the in-game pop-up menus?

Thanks
Johan
