A Python script to validate:

def check_program_nca(nsp_path):
    with open(nsp_path, 'rb') as f:
        # PFS0 header at 0x00
        magic = f.read(4)
        if magic != b'PFS0':
            return "Not valid NSP"
        f.seek(0x10)  # File entries offset
        # ... parse each entry's offset and size
        # For each file, check NCA header at relative offset
        for entry in file_entries:
            f.seek(entry.offset)
            nca_magic = f.read(4)  # Should be b'NCA3'
            if nca_magic != b'NCA3':
                continue
            f.seek(entry.offset + 0x4)  # ProgramType byte
            ptype = f.read(1)[0]
            if ptype in (0x00, 0x80):
                return "Found Program NCA"
    return "ERROR: Missing programtype NCA"
