Final Fantasy IV: Complete Collection

[aturtledoesbite]

I have all those codes (well, except the bestiary one; that's new), and none are what I'm looking for. You might think the Fat Chocobo code would, but that's only applicable to the FFIV half of the game; After Years doesn't have the Fat Chocobo.

EDIT: Should mention, though, that the codes there (at least, the item drop and EXP modifier codes) do work; I've been using them just fine.
