    Of what use is seeprom file.
    While just playing around i thought.I'll dump seeprom with 5.5.2 and compare with 5.5.1
    I noticed 2 differences.

    Then i thought i wonder if there are differences with users on same system. So i dumped it again with different user. And this time different again.
    0000010 - 08 was 12 and 09 was 88 in 5.5.1
    0000010 - 08 was 15 and 09 was 2B in 5.5.2

    The details of the SEEPROM are available here: http://wiiubrew.org/wiki/Hardware/SEEPROM

    The particular bytes you mentioned is part of the 8-byte field at 0x12, which is the RNG seed. It's incremented every time IOS-CRYPTO starts.
