How to extract NCA patch file?

[Kimi-Arthur]

The tool is very useful that I can extract all .nsp files I got. But I only succeeded in extracting .nca files for base game.

For all patch/update, I got the following error:

[NCA Header]
  Format Type:     NCA3
  Dist. Type:      Download
  Content Type:    Program
  Key Generation:  0
  Kaek Index:      Application (0)
  Size:            0x926a400
  ProgID:          0x01001d900d9ac000
  Content Index:   0
  SdkAddon Ver.:   v134348800 (8.2.0)
[PartitionFS]
  Type:        PFS0
  FileNum:     4
  MountPoint:  program:/code/
[WARNING] NCA Partition 1 not readable. (EncryptionType(AesCtrEx): UNSUPPORTED)

One example would be this file, where the extracted file with name 8759c093c9ac45ba455929e61d4a0195.nca cannot be further extracted and will produce the error above.

I'm sorry but NSTool does not support patch/update NCA files yet.

It's planned for the future though.
