	~~These input buffers are the same buffers used with [[AMPXI:ValidateDSiWareMovableSedHash]].~~ This calculates 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.		This calculates an AES MAC over the 0x20-byte buf1 SHA-256 hash. When this MAC matches the MAC stored in buf0, result-code 0 is returned, otherwise an error is returned. This is used for verify the DSiWare section's metadata MAC after decrypting the payload data.
