There are buttons that can be defined in the mainmenuoverride.res that do not have to be defined in gamemenu.res, but I don't think I've seen it the other way around. Which buttons are you talking about? Also in the third picture, the file is called quickplaydialog.res I'm pretty sure. If you want the radio buttons that are supposed to appear for that specific panel you have up, make sure you have this in your in your clientscheme.res with the rest of your fonts:
"Marlett"
{
"1"
{
"name" "Marlett"
"tall" "20"
"weight" "0"
"symbol" "1"
"range" "0x0000 0x007F" // Basic Latin
}
}
"MarlettSmall"
{
"1"
{
"name" "Marlett"
"tall" "14"
"weight" "0"
"symbol" "1"
"range" "0x0000 0x007F" // Basic Latin
}
}
