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

[luxmaridia]

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.
