|0x0||0x100||RSA-2048 signature over the following 0x10-bytes.|
|0x100||0x8||Normally zero? The second byte (offset 0x101) appears to be 0x01 if system is a devkit.|
|0x108||0x8||LocalFriendCodeSeed. Since the data of the whole file gets copied to movable.sed, this also becomes the first 8 bytes of the keyY there.|
This contains the same LocalFriendCodeSeed data that PSPXI:GetLocalFriendCodeSeed retrieves from memory.
