When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NCA_Format|#NCA]] header signature fails. This also skips verifying the signature in the [[NPDM]] ACID. Note that if verifying the fixed-key signature is successful, and verifying the ACID signature fails, it will throw an error and abort.

When the flag is zero, it will set ret=0 instead of ret={error} when verifying the fixed-key [[NPDM]] ACID signature fails. This also skips verifying the [[NCA_Format|NCA Header]] signature using the ACID key. Note that if verifying the fixed-key ACID signature is successful, and verifying the ACID-key NCA header signature fails, it will throw an error and abort.
