How do I link my games in the 3DS releases of the Oracles games?
Solution 1:
The 3DS doesn't have any actual link between the two games, it's still just using the password system, to transfer back and forth your new items (sword and shield upgrades, the biggoron sword etc). Just remember that the passwords are generated on your specific game, based on where you are at in the story, what items you have, what you named Bopin and his son etc etc etc.
On the plus side, you can exit to the home screen, open the notepad and write it down now!
