The application needs to be improved, it is still in early stages of development, it has several limitations and bugs.
Source code of the first version:
http://github.com/tony56a/crp-parser
It has been enhanced by another user known as Tailgunner and is now in version 0.2
http://github.com/clausthaler-devel/crp-parser/
Certainly with the contribution of experienced modders this unpacker can be much better in the future.
