Hi, Counter-Strike: Online (Nexon) has been using a .nar file format since its release and we have been able to decompress the files thanks to CSOTools made by Da_FileServer. However, today's update brought a new file format named .pak. I've already tried using the same decryption algorithm (to see if it was the same but with a different file format), but didn't work. Then I tried to use some old .pak extractors that were used to extract .pak in Doom/Quake/Half-Life's days, but to no avail. So here I am to ask if you could help me decrypt these files.
Here's some samples:

Thank you for your help in advance!
