    Only if you back up the whole "Nintendo 3DS" folder.

    I had my previous Nintendo 3DS folder on SD, but the formatted nand after arm9 setup cant read it. I still have my old folder stored, is there a way to make the system recognize it?

    JK Save Manager allows you to extract and transfer a lot more things than previous programs did--it is now possible to transfer Streetpass Mii Plaza progress without manually decrypting or dumping anything.

    So we just need to figure out which saved data you need to dump in order to transfer Activity Log. Then create an EmuNAND on a new card, restore the SysNAND backup to it, and use JK Save Manager to dump it.

    The problem is that nobody seems to know exactly what to dump. Someone already tried Activity Log near the end of that thread. F000000B includes icons for the software library in Activity Log (and Mii Plaza), but there is something else necessary as well.

    I haven't tried transferring between systems, but I know the Activity log uses system save data. Maybe the system save data + icon cache in f000000b?

    IIRC, the savegame for another system app called "PTM module" is also involved, it contains a log of steps and titles played:
    https://3dbrew.org/wiki/PTM_Savegame

    Edit: If you delete the Activity Log save, the next time it is opened, it will be rebuilt from the PTM one. This can take a while and it will display a loading screen.
