    I downloaded some HANS romfs archives of undub games lately and they worked fine with HANS. Howerver, when I try to unpack them with ctrtool, it appears that IVFC headers of some of these files are missing. After checking them in a hex editor, I found that they don't have "49 56 46 43"(IVFC) as the first four bytes. Is it possible to unpack a romfs archive without an IVFC header?

    Maybe because they are old archive with the first 0x100 bytes cut, when HANS needed it.
    I don't guess you can extract them.
