* Remark: every byte value starts at 0x01 not 0x00.
Let decompose Platform ID as aa:bb:cc:dd:ee:ff:gg:hh.
* aa = type: 01: Syrup prototype, 02: Cavern prototype, 03: standard PS4, 04: PS4 PRO HAC prototype, 05: PS4 PRO NVX prototype
* bb = unknown
* cc = equivalent of product sub code: 01: SAA, 02: SAB, ... 06: SAF
* dd = unknown: always 01
* ee = unknown: 01, 02 or 03
* ff = unknown: 01 or 07
* gg = ?color?: 01, 03, 04, 05, 06, 0B
* hh = unknown: 01 or 02
