This calculates a SHA-256 hash over the 0x130-byte data from [[FSPXI:ExportIntegrityVerificationSeed]]. When the calculated hash matches the hash stored in buf1, result-code 0xC8A0802E is returned, otherwise result-code 0xC8A0802F is returned. | This calculates a SHA-256 hash over the 0x130-byte data from [[FSPXI:ExportIntegrityVerificationSeed]].

The 0x10-byte buf0 data is copied to internal memory, however this data is not used after it's copied. | The 0x10-byte buf0 data is copied to internal memory, however this data is not used after it's copied. This command is used by [[Application_Manager_Services_PXI|AM]] module to verify the hash stored in the [[DSiWare_Exports|DSiWare]] export header, when AM uses this command buf0 contains the encrypted AES block from the header. | ||
