GAR + Moe= Instant Win.
After some Internet Dorama because of a leaked patch by one of the beta testers, Mirror Moon (the group behind the translation project) has finally decided to release the official translation patch for the UBW route. And more, they have included some extra goodies, like the ability to add voices into both the Fate and UBW routes, provided you have a copy of Realta Nua (the PS2 version of the game), and AppLocale is no longer required if your computer is non-Japanese locale.
The links for the patch can be located in Mirror Moon page. Now enjoy your Rin and GARrcher.
