[Pixie]

So inshort i stopped unpacking game before 3 years  which the Script worked fine for npk files but now i only getting errors i got users talked about in xentax forum but sadly can't go to next pages to know if they figured out how edited it, can anyone help to tell me what to do?

I've encountered this error as well, I noticed that newer archives are marked differently and therefore should be extracted in another way.
I'm currently trying to figure out how to start extracting the newer archives.

I figured out the new encryption they're using with the help of a reference.

Here's the updated QuickBMS script, let me know if you have any issues.

I just tested all Identity V archives and experienced no errors. Can you provide details about the archive you're trying to extract?

When I tried using it with the Onmyoji game file, it got this error

 

[TeaEffTeu]

Unfortunately, Onmyoji is not yet supported. Could you send me a sample archive to test with?

Because this file is quite heavy, I can only upload it elsewhere

After several attempts to brute force the alternate encryption algorithm, I finally figured it out after a simple change; Type 2 Encryption is now supported.

Additionally, Onmyoji is now supported.

Thank you so much!!!!!

Can you try to extract the script .npk file of Identity V and decrypt the contents?

[TeaEffTeu]

If your archives contain type 0/1/2/3 encrypted files, yes.

(run the script, it'll panic if your archives aren't supported; if you experience a panic, please let me know and provide a sample.)

Hey TeaEffTeu! I need your help again. I used all the nxpk files I had to extract Harry Porter: Magic Awakened game, but it seems like it's either corrupted, or not supported...

Sorry for bother you, but I really couldn't find anyone to solve this problem T_T.

This is my sample archive.

Hi, I hope this reaches you as you're the only person working on these sorts of things that I was able to find. I've got an example .npk from the Lord of the Rings: Rise to War Netease game and I'm hoping you're able to figure out. Thanks.

If anyone else is able to point me in the right direction for this sort of thing I would appreciate it.

Here's an updated script that is less panic-aggressive (but now more prone to crashing). The script will now ask you what game you're extracting, Identity V (excluding the test server) and Onmyoji are currently supported. Unsupported games can be forced with no guarantees. I cannot deem The Lord of the Rings: Rise to War as "supported" due to my limited knowledge of it, (though I did manage to extract your sample using the "0 - FORCE" game selection).

I tried figuring out your sample's encryption method, but it's taking too much effort. There might be a really simple solution, but I am too stupid to figure it out.

I give up, for now.

You are the best! I have the .dat files and it looks like I just need the RMAViewer program. Heres hoping the xen-tax archives come back up soon.

Hope this helps! I don't rip the same game but RMA probably behaves the same way so; don't load more than 400-500 dat files at once in it or it's going to crash a lot. Not a very stable program.

Thank you! I found another version of the RMAViewer, and it has a .dll that seems to fix the crashing issues. I'll attach it for archival sake.

This is the same EXE+DLL.

Ok, clarification. I'm unsure why the DLL is missing from Dollie's upload, but JumpinGopher's upload has it. I didn't bother to check Dollie's upload until I sanity-checked both uploads (this is the first time I've seen the program missing the DLL). JumpinGopher's upload is the intended distribution of the program, and it still crashes regardless.

Hmm not sure why but I haven't had issues even without DLL. It works fine when loading less than 300-500 files though with minor crashes. When going over that number it crashes more often. Seems it does this with and without the DLL though.

Unfortunately, the script does not support NPKs with the EXPK signature. Here are some tools that may work for you (neither are perfect).
