Read section 3 of http://aluigi.org/papers/quickbms.txt

You must select the SAME file and folder you selected during extraction which is not what you did.





Hi aluigi, thank you for your help. I already understand about extract, edit, and reimport. But I need your help again. How do I make the files that I have edited in this npk file can not be extracted by others or how to code for files that I have modif this is not easy to read other people. Thanks for your help

i got some error with this code :
Code:
Error: impossible to write 0xcf35d200 bytes (total 0xcf35d200)

Can you provide the exact name of the game?

It's not encrypted but the format is slightly different.

P.S.: the lame title of the topic was given by me while moving posts... what a mess.

It's a zip file so use 7-zip or any preferred archive utility supporting the format.

Ok, I managed to extract it. Aluigi I want to ask again, now every game is protected by anti-cheating, do you know that the anti-cheating location is stored where in the obb file?

Could you please upload the original npk archive?

In some occasions there were some npk archives with encrypted TOC (the information about the archived files) while in this case all your files seem obfuscated and apparently start with same sequences of bytes (but I simply gave them a very quick look)

So the script works correctly and extracts all the files but they are obfuscated in some way (start with bytes like 7a 1c, their flag is zero so it's probably specific for this game only).
Unfortunately there is no solution if somebody doesn't provide the algorithm and the key.

This is just a new topic in which I have collected all the ROS-related topics open till now because they are starting to be a lot.

The script to use for extraction and reimporting is:
http://aluigi.org/bms/nxpk.bms

Currently it looks like the files of some recent versions of the game have an additional encryption. There are no updates or solutions at the moment.

Please use this topic if you have updates or questsion, do NOT open new topics.

Sorry if the topic will be a mess but it's better than 10 different topics.

@sunrithy111
You are off-topic. I will keep your post just in case someone is going to ask the same but please no OT discussions.
