An earlier answer posted here said to check GameShark.com. NEVER check GameShark.com, in my experience the codes they post don't work 9 times out of 10, and Blue Moon is not an exception. None of the codes on GameShark.com work for Battle Network 4. Go to GameFAQs, check FAQs, and check the codes there. Though for the sake of simplicity, try using this:
