Well, unfortunately it was the first thing i tried (the quotation marks). I had no error but it changed nothing to the text in the game.
For example i modified
A Map<<n>>Shows visited Places.
Une carte<<r>><<n>>Montre les lieux visites.
A Radio<<n>>Used to listen to Music.
Une radio<<r>><<n>>Pour ecouter de la musique.
A Phone<<n>>Used to call People.
Un téléphone<<r>><<n>>Pour appeler des gens.
I think that it has to be done like that, no? And well, it modified nothing :/
Also, i dont know if it is linked, but when i tried to put the name of a file i hadn't, like pbLoadMessages("inl.dat") (without the "t"), it did nothing at all too, not even saying me that the file doesnt exist ^^'.
