Like my last post, this is something you can buy to “enhance” your AC:WW game by using codes. You can check out the featured Animal Crossing Wild World page on Code Junkies Website. You can buy the Action Replay DS here. It comes packaged with software you can use on your computer to update it with new codes. There’s pre-made codes made for almost every DS game, but there’s also a manual code entry which you can take codes off the internet (or make your own), and put those into your AR. I already have one, and have used it a bit, but probably wont much more. Enjoy!
