Here's the error/warning I get when trying to extract the patch program NCA with the base NCA set to the base program NCA.

$ nstool --tik ../base/0100800015926000000000000000000b.tik --tik 01008000159268000000000000000010.tik --basenca ../base/1a71b5f44572da51fa84023287b7b336.nca -x 9c53271e684dbf9d14acafafb5723b76 9c53271e684dbf9d14acafafb5723b76.nca

I know the patch isn't actually corrupted, as it also runs just fine with emulation. This used to work with an older patch, but I don't know what changed.

Interesting, sadly the cause isn't obvious to me. If the Root sRomfsDirEntry is corrupted, it could be a decryption error or an issue with processing the patch.

Idk if I can help without having the patch & base NCA to investigate. But tbh my time to work on this has reduced a lot recently.
