    I'm just wondering where does the parental code is stored. I'm going to explain how to recovery parental code w/o master code.

    I found the code on system setting save. it's not encrypted like psp.

    Use godmode9 and go to sysnand/data/unique id/sysdata/
    00020200 for jpn
    00020210 for usa
    00020220 for euro

    https://3dbrew.org/wiki/System_SaveData

    Open 00000000 file with hexview mode then go to offset 000060F4 or D0F0. then you can see some secret.

    POC screenshot here.
    Warning: Spoilers inside!

    I confirmed this on my Japanese new3ds. maybe the offset is bit difference on other region. if so please comment and let us know.

    Thank you.

    Need more investigating.

    I'll wager a guess that it's the parental control PIN.
