What happens when I share Wi-Fi games with a friend for use on another Nintendo DS?
The Nintendo WFC ID and the game card are treated as a unit. Because of this, playing your Nintendo DS game card in another Nintendo DS system may override the online information saved to the game card. This would include changing the Nintendo WFC ID associated to the game card as well as your own personal Friend Code. Other players with this Friend Code would no longer be able to identify you as an online friend until you provided them with the new Friend Code you would need to generate. However, the Friend Roster will remain intact. If you are planning on going online with your Nintendo WFC-compatible DS game, we recommend against using the game card in anyone else’s Nintendo DS system.
