Btw, a tip for making the MTL tool work with mods that use the same or similar translation support as the game:
Place a Game.exe in the mods root folder. It just needs to exist, it does not need to be a valid file.
For example: to make the MTL tool work with MCM/CMF, place a Game.exe in the ModScripts/_Mods/Cheats Mod/ folder and point the tool at that Game.exe
If the target language already exists in the mod, the tool will simply copy that language from the mod to the MTL folder for that mod, translating any found CHT to the target language in the process.
The only caveat is that there must be a CHT translation (native or otherwise) or it will not work.
