codes are not working or game freezes usually are caused by using the wrong version , wrong region of the game or the address is dynamic or other reasons ( street pass data , dlc, yes or no save file)Oh I see I will try this one then thanks ^^
The codes finally loaded but the balloons are not showing up for free for some reason and the game froze after scrolling down :/
but, as long as you get an error from the browser, that means the exploit works on your firmware
