"Dragging an dropping a koi code into the game doesn't do anything"
Have you tried the koi code on the store page? Looks to me as if codes cannot be imported back into the save that exported them, which feels intentional.
Huh, that's weird - the one on the home page does work. In that case, I can't just store my koi in codes then - so an alternative is needed as the book as limited space. It should at least show a message rather than do nothing.
