UNS4 encrypted files

It's my first attempt before doing stuff on ZMod3. Of all 3 CPK unpacker softwares I tried, one is a great success, straight from its build origin I found on XentaX long ago, but here's the thing.

Encryption is what people said about this game. Although CPK files are extracted no problem, its insides are being a problem. Hear this, I've been poking around several CPK files and found data1.cpk inside "launch" folder. The unpacking process had no problems, but trying out either with Noesis or Zealot's UNS Model Editor... either cannot be opened or "not a valid xfbin format" message show up. So I checked the contents with Notepad++ and its header are somewhat unrecognizable. I hooked up Google before writing this stuff up for ways of decrypting these raw files and do the job like some of those folks did in either San Andreas or V, and what I found out is true: despite CPK files are decrypted for this NS:UNS4 game, its contents are otherwise (encrypted). Few people already attempted to do this decryption thing on the files, but only a handful of people did in one forum, either ZenHax or the one I found CriPakTools at start, XentaX.

This raises me question: modding is possible out there for these UNS series of games, but there's this mod that rips the UNS4 Road to Boruto DLC expansion models and things straight towards UNSR (Ultimate Ninja Storm Revolution) as a part of the mod, so how come the dude who made this can do it? To be frank, if this dude can do the mod, UNS4 somehow has a decryption software capable of doing it.

Honestly, the majority of the mods for UNS series of games are come by decrypted. I've seen them myself after I got some mods for both UNS4 and UNSR to try out and checked out its contents today with Notepad++. They have a header that says "NUCC" in all XFBIN files, whereas the one that I extracted yesterday straight from UNS4 are somewhat not a header that I was expecting, like an instance of WannaCry encrypted files that sadly none of the decryption softwares are exist until today (or maybe there's one today, idk). This forum thread might explain you all about it.

I've searched further about this and the decryption method of these raw files until I stumbled across a Chinese dude who found a BMS file - apparently for use with QuickBMS program, after that simple Google Search - "misinterpreted" the use of it as a "thing" that extracts CPK contents. I never heard on what forum thread he was reading, and he just found it right in the open, tried several ways of decrypting the sh*t like I do, but no luck. His last post was on September 2 years ago since this writing. This forum thread will explain you.

I've checked the contents of the BMS file I downloaded; the beginning of the content said "Naruto Shippuden: Ultimate Ninja Storm 4 - decrypter". The first, idk what's the purpose of this being made, but as soon as I go to another forum thread on the same website, another BMS file was there again - the same purpose as the CPK unpacker do - with something that said "quickbms" in one of the posts. That's where I got the QuickBMS program from that word I hooked up on Google.

Kinda desperate for the guy named SergioM3 on YouTube because he didn't want to share his decryptor tool with the people - many people have asked for it. I checked his Twitter; no posts said about the link to the specific jar file I want to try out. He did said in a video that he knows YouTube policy and avoided to share the download link, but this is what I'm asking questions: they released mods like those I tried with the download link included, but why this guy don't? Cared about losing the account?

I found external links, if not phishing or harmful, could not affect the video - that's a new policy that YouTube updated a year ago or somewhere, and cloud storage sites? Google Drive, MediaFire, and some others could not be suspected as phishing or harmful. Maybe; just maybe, though.


I might have a better luck trying the already made methods to decrypt the files, but if that doesn't work, let's see if I can gain luck by ripping out the already made UNS4 and UNSR mods into GTA, or program a decryption myself - needs extra learning for that, though.
