Discussion / controversy / speculation and dreaming

Looks like 3 "counters" with a length of 2 bytes each. Yet being the first and second value always equal. The value stored is in decimal (note when values increases over 99), and increases chronologically based in release/repair date

Are not hardware identifyers because refurbished ps3's uses big values (ps3 models that had some kind of "software surgery" in a repair center)

  • Speculation... target stuff to "count"
    • datecodes/months/quarters
    • loaders/firmware ID's
    • sizes (of something that always increases)
