    I heard that you will lost save data if you change headers. Is that true? I ordered a Sky3DS. My firmware is 9.8 (N3DSXL) if this info matters.

    Save data is encrypted by the unique ID in the header of the rom/cartridge
    So yes, you will lose your savegame

    The only way to keep it:
    CFW and SaveDataFiler, or NTR CFW + SaveData plugin
    (these both require a 9.2.0 or lower 3ds/n3ds)

    Darn.... How about backing up the save in diskwriter? I remember seeing an option to do so. There is "Back up save data" and "Restore save data".

    That will only back up the encrypted save, not the un-encrypted part that needs to be injected into the new save

    Darn. I guess I cannot switch headers later on so I have to choose a game I won't go online often. Since I couldn't extract the header from my offline game (Super Monkey Ball 3D), my second choice would be Pokemon Y. Is it safe to go online with Pokemon Y as long as it is not online at the same time as my Sky3DS?

    Yes, It is safe to play online with A shared header as long as only one console is using at at a time.

    I used your powersave method. Both methods have been used multiple times. The game is not supported by action replay if this info is necessary, but I'm pretty sure thats just for codes. The game is bought at 3DS's launch day.

    The 48 FF bytes don't seem to be there, even when scrolling down.

    If the game isn't supported by powersaves (has no codes) then it doesn't fetch the uniqueID because it's unnecessary because the save Isn't being modified, only copied.

    If you really need the header, you can mail me the game and I'll dump it for you. (and mail it back of course)

    I sell them for $10 and for an extra $10 I'll convert your saves for you

    No wonder. Is there anyway to extract it though? If every game has a header, and is possible to be extracted by powersaves, there must be a way.

    Ripping the games with the gateway launcher (requires a <9.2 console) It will dump the full rom including the header.

    Dang, I got no choice but to rip out one of my other roms. It would be rather Animal Crossing or Pokemon Y.
    I heard that games have different manufacturers. 90% of the games have C2. If I remember correctly, Animal Crossing is AE, and Pokemon Y is C2.
    Would I be better off using Pokemon Y?

    Also, one more question regarding patching template with NoBanNoSky:
    After extracting the header, you paste it first 16 bytes in a blank template file from your guide.
    When using NoBanNoSky, do you just select the Sky3DS template, and the Private Header template, and then patch without selecting a ROM?

    How about when a new Sky3DS template comes out?
