I just found this a few days ago. Now before you go all crazy and say "No!!!!!!!! patches = piracy", this one works different, and doesn't require a backup to mess with. You need homebrew(which as of now is perfectly legal btw), and it patches the game directly from an SD card. So you need a legit copy that you have imported/bought, though I guess you pirates could do it too. This is pretty amazing that it only took them a few months(they started around april I think) to translate the game. Right now it is at 90% complete and should be done any pretty soon. I originally was going to wait to import the game and play it when I get more proficient in my Japanese, but I'm glad I waited for this. Now my copy is on the way. They are also thinking about translating it to other popular languages.
