Can someone check out "Port Royal 4"

Would be nice, if I can import files as well.

It is "FUK" as ending, but it uses a Win64-Shipping.dll so it uses some kind of Unreal Engine for sure?

Uploaded example here:

@Pepita: https://blog.kalypsomedia.com/en/port-royale-4-faq/ -> "What engine does Port Royale 4 use?". You can take a look at this topic, maybe format is still the same.
EOS SDK dll is Epic Online Services library, used by EGS in games from the store (like steam_api.dll in steam games).


@mage200: You can't just open uproject in Unreal Editor, because all assets in pak archive are "cooked" (serialized) and editor doesn't understand them. If you need only models, use umodel.
And what do you mean by decompiling uplugin? This file is plain text config for UE4 plugin, used by the game (like ini file). You can change some options in it, but most of them will be ignored, since plugin's code is being compiled into main game executable (except some third-party libraries) and most of their parameters are hardcoded in the process. At least, I never saw someone using this stuff for mods or anything.

I used this instruction to pack back to the .pak archive

https://gbatemp.net/threads/how-to-unpa ... es.531784/

But I do not understand these actions:

4.2. For Find what: paste
Code:
" offset: (.*)$
Replace with:
Code:
"
Click Replace All

When all my lines look like this:

cove_sequencer.uasset" offset: 0, size: 13248 bytes, sha1: 45D1F87013C099A1B33CADDE00B0D5DD6DA0A889.

I need to replace strings like this

" offset: 0, size: 13248 bytes, sha1: 45D1F87013C099A1B33CADDE00B0D5DD6DA0A889.

on this

"
?

@Bafteam: If you need to use unrealpak, I suggest more simple solution - like this one. And also read this post, it may help you as well.

Thank you, but I figured out the link that I threw off. The problem is different, the game has an archive check, the game gives an archive check error at startup, if you just repack the .pak file back to the obb. You do not know what to rely on in the .so library when searching for verification?

Question: Is there a way for unpack Movie or CG when they are in the the .pak? I am trying to unpack the Samurai Showdown Intros, because they are movie, not textures as I open and search every archive using the UE Viewer and hadn't not see anything like what the movies in-game look like.

@GabrielProudmore: umodel doesn't support some assets, usually present in game archives (maps, movies, scripts, localization files and others), that's why you can't see them. Simply extract all assets from paks with quickbms and latest UE4 bms script and you'll find movies around SamuraiShodown\Content\Movies - but only if they're pre-rendered.

@Bafteam: So you're 100% sure that you packed it back correctly, right? Well, it's not an easy question even for pc games. I was planning to dig into that after I'm done with aes keys on android, but here are some thoughts (valid for ue4 games on pc):
1) For almost all games you can't repack base pak, only add modded one, usually with archive version less than used by the game (probably because checksum is being integrated in main binary during compilation). And you should also pay attention, if original game archive has standard format or not.
2) There is such thing as signing. I don't have an idea how it's implemented on android, but on pc it's possible to re-use existing signature, because UE4 only validates signature itself, not the related pak integrity (unless specific check is added manually). Though I can't remember if I even saw signed pak on android.
3) It's worth to check UE4 source code for responsible parts (IPlatformFilePak and SignedArchiveReader) to find out is that error belongs to UE4 core or it's due to additional changes by devs - btw, you can find out where this error is occurring by searching for the string in libUE4.so via IDA or something. If it's from core part, there is high possibility that you've messed up with the pak, since those checks are mostly to prevent a game using incompatible/broken archives.
4) If the error is not from UE4 core, it may belong to side checks (especially on android, since UE4 is present as library there). In that case this check can be anywhere - in main classes, other libraries, etc.

Actually, basic check for this kind of stuff would be simple repacking original assets without modifications. But even before that I would try to create mods instead of repacking the whole archive and check it out.

I repackaged the original .pak file without any changes, took it from the obb and threw it back and the game says that it cannot find the files to download.

AES keys finder for mobile UE4 games added to the base post: viewtopic.php?f=9&t=1005&p=56251#p56251

Please note that this is just POC (proof of concept) and due to its brute-forcing nature it works much longer than usual finder for pc games (up to 40 minutes). I know that there are more proper and optimized ways to do the same thing out there, but it's out of my league. At least, this solution is user friendly and doesn't involve debugging or third-party software, except JRE.
I'm not going to work on it in near future, except fixing possible critical bugs and adding support for custom paks. Feel free to leave your feedback on rin forums though.

Specific scripts bundle updated with Dragon Quest XI script (thanks to infogram) and also with the fix for some additionally xored normals from the game (more about the issue in this topic).
You can find the bundle in the base post: viewtopic.php?f=9&t=1005&p=56251#p56251

For research purposes, is it possible to get the AES Key for [PS4] Days Gone?

@zeaofsuos: Game archives are not encrypted. If you're looking for passcode, the default one is fine (xiB6LnPxcxIDl2CrCJC7eBnZ1wQXvjNm), though it works only on the base game and some early patches.

My bad. I unpacked the PKG first then tried the script; unreal_tournament_4.bms on the games, "chunk1.pak" PAK files but I encountered the following error;

@zeaofsuos: That's strange. Last time I've checked the game all was fine by default. Try latest UE4 bms script from my signature, if it will not work, use filecutter script on any pak and upload resulting files here.
