This won't be supported. There's no way to save an encrypted archive. The first 80 bytes of the header are encrypted with RSA-1024 (i.e, public/private key pair). We can only decrypt, we'd need Codemasters' key to re-encrypt this data. This section of the header has the expected hash of the archive, if its incorrect the game will crash.
