=== Hardware key generator ===

A dedicated hardware key generator can be used to generate a keyslot's normalkey from its keyX and keyY by enabling the corresponding bit in REG_AESKEYCNT. If enabled, the hardware key generator is triggered by writing the keyY (which also seems to be the only way to trigger it). The algorithm used for key generation is unknown.

Unless noted otherwise, all keyslots on retail units use the hardware key-scrambler.

Starting with [[9.0.0-20]] the Process9 FIRM-launch code now "clears" the following AES keyslots, with certain keydata by writing the normal-key: 0x15 and 0x18-0x20. These are the keyslots used by the New3DS [[FIRM]] arm9bin loader(minus keyslot 0x11), the New3DS Process9 does this too.
