Package ID from #CardHeader at offset 0x110 This region is used for challenge–response authentication when changing to the Gamecard's secure mode.įS calculates a SHA-256 hash over the whole 0x200 bytes and compares it with the hash stored at offset 0x160 in the #CardHeader. Therefore, it is hidden away during read/write operations on the raw Gamecard data. This region cannot be read directly once written to the Gamecard.
