HeadHunter 1CD Version

[sirius5321]

I've already posted an issue about how to use the ppf patch that i've downloaded from www.megagames.com, in this forum but no one as gave a solution. This is what I have:
- Selfboot HeadHunter CD2 (with a error) from ECHELON
- A PPF FIX : DISC2PATCH-HLG-HUNT with this message in a file:
Apply PPF on CDI-Image.
Burn the patched CDI-Image.
The unpatched Image is disc 1, the patched is disc 2.

Is this the correct Patch?
How do I extract the CDI Image: The entire CD or Just the Data?
How do I apply the patch to this image?

Please read my other posted issue, and give me your opinion.
