Header

The header is 0x200-bytes, at Gamecard+0.

Offset Size Description
0x0 0x100 RSA-2048 signature, presumably.
0x100 0x4 Magicnum "HEAD"
0x104 0x4 Offset of Secure partition (Size of non-secure data?), in Media Units
0x108 0x4 0xFFFFFFFF
0x10C 0x4 ?
0x110 0x8 ?
0x118 0x8 Size of the Gamecart, in Media Units
0x120 0x10 ?
0x130 0x8 Offset of HFS0 FS partition
0x138 8 HFS0 Header size
0x140 0x20 SHA256 hash of the HFS0 Header
0x160 0x20 SHA256 hash of ?
0x180 0x4 1?
0x184 0x4 2?
0x188 0x4 0?
0x18C 0x4 Offset of Secure partition (Size of non-secure data?), in Media Units, again.
0x190 0x70 Encrypted data/hashes of some kind


Cert

This is for the CERT, located at Gamecard + 0x7000 (always?). This matches exactly the output from fsp-srv IDeviceOperator cmd 206 "GetGameCardDeviceCertificate".

Offset Size Description
0x0 0x100 RSA-2048 signature, presumably.
0x100 0x4 Magicnum "CERT"
0x110 0x10 ?
0x12A 0xD6 Encrypted data. Some kind of key?

The data between the CERT and the start of the HFS0 is all 0xFF.
