Hi,

I am new on this forum, so I'm not sure if this is the right place to post this topic.

I am trying to extract CG's from the following visual novels:
- Kimi to Kanojo to Kanojo no Koi. (English release)
- IxSHE Tell (English release)

I tried extracting the CG's with GARbro, but the files that contain the CG's seem to be encrypted. I only have basic knowledge on how to use GARbro. I don't have any knowledge on how to use other extracting programs, so I really need some help with this.

This is what I know about these visual novels:
- Kimi to Kanojo to Kanojo no Koi. is a Nitroplus title that uses .npk files (NPK3)
- IxSHE Tell is a Artemis engine title that uses .pfs files (example: root.pfs, root.pfs.004, root.pfs.005, etc.)

@Y-Stylzz: For the first one take a look here: https://github.com/marcussacana/MwareStuff (it has both NPK3 stuff and key finder).
For artemis engine you can try this script: https://aluigi.altervista.org/bms/artemis_engine.bms
If the game is using default encryption, required info will be derived from files themselves.

Sorry for the late reply. It took me a while to figure it out, but I finally extracted the files of Kimi to Kanojo to Kanojo no Koi. Thank you!

However, still no succes with IxSHE Tell. The script succeeds in extracting the files, but they can not be opened. The game probably uses non-default encryption.

Can you explain step by step, how you were able to extract the files? I'm trying to do the same thing and any help would be greatly appreciated.
