FLVictoria Is compatible with map mods, flag frame mods & maybe music mods.
The mods I know this to be compatible with, are: Belle Cartographie (Map Mod) & Big Flag Frames for Victoria 2 (Flag Mod), Both can seemingly run together.
And that's that, here's the link to the previously mentioned mods: Belle Cartographie mod for Victoria 2: Heart of Darkness - Mod DB & Big Flag Frames for Victoria 2 3.04 and HPM addon - Mod DB
Cheers to the creators of those addons & mods.
