Exosphere + Emummc Config (<=0x200)
|
|
Boot Config[0x400]
|
|
RSA Context(0x100)
|
|
Old Device Keys[0x20][0x10];
|
|
Old Master Keys[0x20][0x10];
|

Global Data Page (accessible via X18):
|
|
0x000-0x200: Exosphere Config
|
|
0x200-0x400: Emummc Config
|
|
0x400-0x800: Sealed AES Keys
|
|
0x800-0xC00: Boot Config
|
|
0xC00-0xFFF: CPU contexts. Can be replaced, but this fits exactly so minimizes program space waste.
