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

Knowing PSCode we are able to deduce the 9 first bytes of ConsoleId.

See ConsoleId#Structure) and [PSConsoleId-wiki].

It is get in userland by _vshSblAimgrGetPscode, _vshSblAimgrGetPscode2, and used by sceRegMgrSrvCnvRegionPsCode.

It is get in kernel by sceSblAimgrGetPscodeForDriver, sceSblAimgrGetPscode2ForDriver, and used by sceRegMgrSrvCnvRegionPsCodeForDriver.

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

but also in userland to detect the region by the TargetId that it embeds.
