How to ripping .pkn file about [Nexon Bubble Fighter]

[xognsrla0102]

Hello. I found this site to extract the Korean game Bubble Fighter.
When you download the game, Bubble Fighter and associated client data will be installed on your computer.
These files have a ".pkn" extension, and if you try to extract them with gameripper.exe, most of the file processing will be completed within 20ms.
However, when I go to the working directory, no files have been created, and I cannot see the extracted image or related files inside gameripper.exe.
Even if some files are extracted, they cannot be viewed successfully.
help!

I also show you the Bubble Fighter folder structure.

I have attached and uploaded part of the Bubble Fighter client data file.

was not expecting to see someone else who has an interest in ripping this game! as far as I know, only .bfz files work with Gameripper because they're basically .zip files. Gameripper can't rip unknown files/games packages such as .pkn files and it will instead create a blank file if you try to rip them with the program.

Thanks for letting me know!
By the way, How did you get the bfz file instead of the pkn file?
I tried finding some bfz files from the internet, but I still get similar symptoms.
