Nostalrius Begins - Quality wow vanilla realm (1.12)

Hello everyone

I would like to know whether it is possible or not to have the game client in english and in game texts (like spell's description or quests texts) in other langages.
I have already tried to copy and paste the speech.mpq file from an other game client to the english one and it works. That's why i want to know if i can do it with texts (i don't know what to copy).

Thanks in advance

Yes it is possible. You have to change your WDB folder tho, not any .mpq files.

Do you know what i have to change in my WDB folder ?
