Compressed files and methods

Not sure how to extract the images or audio from these files. It looks like they're encrypted. The game uses Unity and the directory formats are "files\dlc\droid\raw", "files\dlc\droid\ab" and "files\dlc\droid\catalog". The audio files have AFS2 headers, but crash when using the QuickBMS script saying this: Error: impossible to write 0xffffffff2942ffe9 bytes (total 0xffffffff2942ffe9) Check your disk space or the script is wrong Last script line before the error or that produced the error: 27 log "" OFFSET SIZE Attached sample files.

Hi all, I'm trying to extract files from a Konami PSX game. The data is in .R2 archives, which are containers (file count at 0x4). The files inside are compressed. The compressed data starts with the magic string "TEN2". This prevents tools like JPSXDEC from finding resources like TIM images, even though they are listed in the archive header. In the script file (SCRIPT.R2), I can see fragmented, readable text, which suggests the compression might not be very heavy. Does anyone recognize this "TEN2" compression format from old Konami games? I'm looking for any information on the algorithm or a way to decompress the files. Sample files are attached…

Hello I am fan translating NANA from ps2, and so far i have been able to replace the first cutscene by decompiling and recompiling the PSS file that contains the first cutscene. To proceed further I need help disassembling / understanding NKT, NKF files. i assume the NKT is text / texture. NKF is the font files i need for remapping all the SJIS chars into english, and adding missing / needed characters. If anyone could provide me with some dissasemmbly knowledge or a tool on how to decompile / view these files correctly, please contact me @mxlg discord, @mxlgborn telegram. Thank you! here is the cutscene: https://files.catbox.moe/cemfep.mkv

The file doesn't use the regular Kirikiri 2 encryption. It's a data file from a cancelled game. It uses encryption from https://type74.org/ed.php (specifically version 3.4) but I have no idea how to crack it. I tried to decrypt it with xor, but it doesn't seem to use xor. Not sure what encryption it actually uses. Included a second file (ane1177.zip) as a sample of the encryption. data.zip ane1177.zip

Hey guys, how are you? I hope you're well, is it here that people have their minds unlocked in the matrix? 😆 Jokes aside, I'm trying to extract some files from this game: https://www.icarusonline.co.kr/main , and an old game made in CryEngine 3. the file format is .pak or .npk, an old program called PakDecrypt was able to extract files from it just using the RSA Key, but in 2024 the encryption method was changed and since then it is no longer possible to extract files. I would like to know if anyone would be able to figure out what obfuscation method was inserted into the game, you can say below how far I got, but I lack the skills to go further. This …

Hi, the files to this game are encrypted, but I couldn't figure out what algorithm. It's not xor, and I'm not sure how to proceed from here The game uses Unity 2022.2.11f1 2 sample files provided ac.zip

Hello everyone, I have been struggling for some time to extract the assets from the .vfs file in the Steam folder of the game La Pucelle Ragnarok. I am trying to get the sprites of the game since some aren't on spriters-resource.com I tried using Ninjaripper, Renderdoc, Special K and Dragon Unpacker. The later gave results, but I only managed to get sound files. For the pictures, no matter the software, I only get some glitched, negative gray scaled or red scaled ones. My best bet is Quick BMS but I need the good encryption key... I tried this list of keys but the La Pucelle and NIS keys don't work with the Steam version of the game (NIS being the develope…

These are two files with the same suffix that I extracted from the reverse UE4 game pak file. But one of them should have used some kind of compression method. I know I should use the umodel tool to extract it, but umodel does not support saving files for this game. I hope to receive help, thank you! This is a file without compression, I have provided it in the attachment. I can clearly see the file tag ,version,data... This is a file that has been compressed in some way. I can see some data with the same tags and versions as the uncompressed file. The file header contains fixed bytes such as 0x8C06. I'm not sure about the s…

Hello. Included are three archives that, were they uncompressed, I would be able to extract from, being PVR textures. Unfortunately, this kind of thing is well above my head. Help would be appreciated! compressed.zip

Hey, everyone! I recently re-discovered an old game available on the Xbox 360 Live Arcade back in the day called "Hybrid", developed by 5th Cell. I managed to extract the files however textures, models and sounds are compressed and not recognized by any tools. For instance, the .MDL files are compressed with LZMA as far as I could see in the file headers. I will upload a sample of each (sound, model and texture). Best regards! Hybrid_Sample_Files.rar

Hi everyone, I'm running into difficulties with what appears to be a modified GZIP format from a PS2 game(Virtua Cop) and would appreciate some expert help. Inside a container file (CMN.BIN, attached), I found 5 GZIP-compressed . The last four files have standard 1F 8B gzip headers, and I can successfully decompress them using tools like WinRAR to get valid TM2 texture files. The problem lies with the first stream (offset 0x0 to 0x11DF in CMN.BIN, also attached as unknown.bin). Its header starts with 1E 8A. Interestingly, if I add 1 to some bytes in the header starting around offset 0xA (treating FF+1 as 00), I can see what looks like the original filename…

Wondering if anybody knew how to extract or create some sort of script to extract all data from this disk00.bin file from the ps4 version of Cartoon Network: Battle Crashers This is where all data (apart from music which i managed to locate) is held.

Hello, respected forum folk. The 2008 game Incredible Hulk uses .ARC files that do not adhere to the usual .arc format and I have been struggling to crack them open. I wish to be able to view and edit the contents to locally "mod" the game if you will. I have done some research and found a tool by cuzitsjonny that extracts the ARC files from a game called Loadout that was made by the same game studio, Edge of Reality Ltd. but this tool gives me an error of "Magic mismatch" when I try to extract any of the ARC files of Incredible Hulk. I haven't undertaken such a reverse engineering project before so I would greatly appreciate any kind of help. What can and should I do?

Is there any tool or script to unpack the .dat files from the Japanese version of Metal Gear Solid 4? I've searched, but it seems like only tools for the US version are available. I want to play with Japanese voice acting, but the game doesn't support Japanese audio with English subtitles. If you can also explain how to port the Japanese dub to the US version, that would be even better.

Hi! The posts (with answers) I saw on this game were from years ago, and I don't think the methods to decrypt the files work correctly anymore. The game now adds CRC3210000000000000000 and 10 random numbers to the header After this is the regular unity header UnityFS. The rest of the file seems to still be encrypted in a way. The old post I read said that at the time the files were XORed, but I don't really have the time to figure out if that's still the case now and they only changed the key. aegis_unity3d.zip

i'm trying to extract all of the files from the Unreal Engine 4.26 (i believe) PS4 version of Marvel's Midnight Sun's. FModel works but i'm extracting a lot of files and it goes super slow. QuickBMS usually works on these and is able to quickly extract them but i'm getting errors and i'm unsure why. I have used the unreal_tournament_4_0.4.26d_paks_only and original unreal_tournament_4 script and none are working. I have uploaded the files of 2 different examples, both including the, PAK-UCAS and UTOC file. https://gofile.io/d/TP8vOq

Hello! Need help with saves of the game Disney Dreamlight Valley. If I understand correctly all data are in profile.json, also there is a file keychain.json, perhaps it is somehow connected with encryption. Initially my goal was to see if it was possible to manage some game quests through a save file. But as it turned out to read it is not so easy:) I attach an archive with my files, there are only 2 files in it, because the rest of them do not play any role for sure: steam_default_r.zip the structure of the game profile folder is as follows:
