By codes, I'm guessing you mean Wondermail codes. Check the pinned topic at the top of this forum or click on the link below.
http://forums.supercheats.c...1&page=1 Remember, and discussion about helpful codes or how they work can be posted there. I do believe the answer to your question can be found on the first page.
If, by some chance, you weren't talking about Wondermail codes, then forgive me for doing this and simply explain what you did mean in the pinned thread.
