This is more easier (and faster) than deleting/renaming files and folders manually for play in the language you want.
Just put the exe in the same folder as HackingToolkit, and run it.
Enter 1 if you want play in French, then you have just to rebuild your RomFS, then your game.
Enter 2 if you want play in German, then you have just to rebuild your RomFS, then your game.
Enter 3 if you want play in Italian, then you have just to rebuild your RomFS, then your game.
Enter 4 if you want play in Spanish, then you have just to rebuild your RomFS, then your game.
@Traiver : Feel free to add it in your post if you want, instead of all your steps ^^'
