PSCode

The PSCode is a 8 bytes code that contains console specific information. It is derived from the ConsoleId.

Knowing the PSCode of a console, we are able to deduce the 9 first bytes of its ConsoleId.

See [1] and PSConsoleId-wiki.

It is used by non-secure kernel and usermode to determine the model of the device: - IsCEX, IsDEX, IsTool, IsTest - IsVita, IsDolce, IsGenuineVita, IsGenuineDolce
