Quote this post for codes!
I'm an Australian who sometimes imports from UK to save money. Sometimes the European codes work in Australia, sometimes they don't. These ones didn't. First person to go at it gets 'em!
I believe they're for Sonic Lost World, Wind Waker HD and Bravely Default.
The good news is though I have just over 7400 points (years of saving, we never get anything decent lol) meaning when that amazing Luigi's Mansion figurine comes out in Aus next year I'll be able to get it.
(if there's a way I can use these in Australia please be a good samaritan and let me know before using them ;_; haha)
