ROM Hack Question How to extract Delta Fragments?

[Domineu]

I recently stumbled across an update NSP with 6 bigger NCAs (each ~128MB) along with the main NCA. Turns out they are Delta Fragments and it looks like I can't extract those the same way I extract the main NCA, so I wonder what they do and how to extract those.

You dont need to, just extract the main NCA.
