Hi there, I just dumped my own private online header, just want to ask some questions. I am on version 9.2:-
1. IS there any chance that Nintendo might do so that we have to update our console and then only we can access internet on 3ds? If so, what is the best option to do now to run Gateway?
2. I have played Pokemon and some other games without header, so, when I just put the header on that rom, I think the save file will get corrupted. So, what I can I do to retain my save? And, can I do the same method on all games?
3. Is there any way, after creating emunand to retain saves of legitimate (cias) ?
4. If I would have to downgrade, what do you think should I do first, create emunand and then downgrade or vice-versa?
5. Can Nintendo see that whether we are using DS Profile Exploit when on Sysnand 4.5?
6. After creating and unlinking the Sysnand and Emunand, does the friend code changes?
Thanks for anyone answering my questions.
It would be really appreciated.
