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), so the New3DS Process9 presumably does this too.
