I have a 2ds which comes with Mario Kart 7. I would like to put CFW on it. My questions are, if I purchase the 2ds with MK7 pre-installed: 1. Will I lose the game during the CFW process? 2. Can I back the game up before the CFW process? 3. If the game does not get lost during the CFW process, can I back it up after? I have previously made backups with godmode9. Thanks!
