How do I localize new unit names for the stock maps in BF2?

[saber91]

I changed the super battledroid to a battle droid and the officer to a super battledroid and put their respective names. however when i localize these names it only shows up in my MOD world map. but i want it to show up in all of the stock maps as well. how do i do this? i tried to copy and paste the core.lvl but it just crashes the game.

That's probably because you're missing something in the req files. Make sure the file size of both core files (new generated one and the vanilla file) are the same
