Combine fmf files for 1 game

Hi !

I've created a fantasy Youth Rating fmf file, with random youth ratings for all countries.
But I'm using a lot of database updates, based on the work of several guys, for championships in countries all over the world.
How can I be sure that my Youth Rating fmf file is really used in my career, among all the other fmf files ? I mean : all other fmf files still have original youth ratings.

Thanks for help

fmf files work by only changing the items edited in them.

So you can have one fmf file moving Messi to Portsmouth, and another fmf file changing his year of birth to 1998. When you start a new game with both files loaded, he'll be at Portsmouth as a 20 year old.

Unless one of the fmf files changes the original youth rating attribute, then the ones in your file will be the ones in the save game.

Hope that clarifies
