Description
These input buffers are the same buffers used with AMPXI:ValidateDSiWareMovableSedHash. This calculate an AES MAC over the 0x20-byte buf1 SHA-256 hash using the same keyslot used for DSiWare exports' MACs. When this MAC matches the MAC stored in buf0, result-code 0 is returned, otherwise an error is returned.
