They looks like encrypted by the same key. Unity bundles have large, mostly static header and this very helpful in our case: So, if simple XOR is used for encryption, we can try to get key using marked ^ part of header, adapted for Unity version used in game: (not sure in highlighted byte and too lazy to check, but it's better to note and change, if errors occurs) XOR have some interesting features: If you XOR 00 byte with any byte, you get this byte value in place of 00 - so, short keys can be visible with bare eyes if encrypted file have a lots of 00-bytes. If you XOR encrypted file with original one - you'll get <key><key><key> sequence on whole file content. We don't have original file, but we recreated first 35 bytes of it. So, i renamed a copy of game bundle to "s1" and XOR it as new "s1x" file using reconstructed header bytes as key, with XOR tool from Luigi Auriemma: xor s1 s1x 0x556E69747946530000000008352E782E7800323032312E332E39663100000000000000 And got partial <key><key> sequence: So, XOR key is: EA7B2B092B59433996F0B470B7B3FEA7BC0AA57B0208A7314420 Decoding test bundle as "s1t" file with this key: xor s1 s1t 0xEA7B2B092B59433996F0B470B7B3FEA7BC0AA57B0208A7314420 Looks very good ) Drag-and-drop "s1t" file to AssetStudioModGUI, and it loads without issues, so key is valid: Dealing with 36K files in cache isn't easy task, so i done a python script for mass decrypt and save to separate folder: # Mobile Suit Gundam - Iron-Blooded Orphans G bundles unxor import os xor_magic = b"\xBF\x15\x42\x7D" # xor key: EA7B2B092B59433996F0B470B7B3FEA7BC0AA57B0208A7314420 xor_key = bytearray(b"\xea\x7b\x2b\x09\x2b\x59\x43\x39\x96\xf0\xb4\x70\xb7\xb3\xfe\xa7\xbc\x0a\xa5\x7b\x02\x08\xa7\x31\x44\x20") output_path = R"C:\tmp\Cache" with os.scandir('.') as file_paths: for file_path in file_paths: if file_path.is_dir(follow_symlinks=False): pass else: with open(file_path, "rb") as work_file: file_magic = work_file.read(4) if file_magic == xor_magic: print("Processing file:", file_path.name) work_file.seek(0) encrypted_content = work_file.read() encrypted_content_size = len(encrypted_content) decrypted_content = bytearray(encrypted_content_size) xor_key_multiplier = int(encrypted_content_size / 26) + 1 xor_key_array = xor_key * xor_key_multiplier for byte in range(encrypted_content_size): decrypted_content[byte] = encrypted_content[byte] ^ xor_key_array[byte] out_file_name = str(file_path.name) + ".unity3d" write_path = output_path + "\\" + out_file_name os.makedirs(os.path.dirname(write_path), exist_ok=True) open(write_path, "wb").write(decrypted_content) print("Decrypted file saved:", write_path) work_file.close() Must be run inside of "Cache\assets\asset\" folder, and output to temporary folder on disk C (it's SSD usualy, to speed up things). But there's other problem occur - that cache folder taken from a game which survived many updates, so a lots of older copies of same file present here, they have same name in first part (before "_") and version code as second name part. So, i done another python script to separate latest file versions to another folder: # Mobile Suit Gundam - Iron-Blooded Orphans G cache sort import os import shutil work_dictionary = {} output_path = R"C:\tmp\Cache\Assets" with os.scandir('.') as file_paths: for file_path in file_paths: if file_path.is_dir(follow_symlinks=False): pass elif len(os.path.splitext(file_path)[0]) - 2 != 52: pass else: bundle_name = file_path.name[0:33] bundle_version = int(file_path.name[34:52]) if bundle_name in work_dictionary: if work_dictionary[bundle_name] >= bundle_version: pass else: work_dictionary[bundle_name] = bundle_version else: work_dictionary[bundle_name] = bundle_version for item in work_dictionary: file_name = item + "_" + str(work_dictionary[item]) + ".unity3d" destination = output_path + "\\" + file_name os.makedirs(os.path.dirname(destination), exist_ok=True) if os.path.isfile(file_name) == True: shutil.move(file_name, destination) print("Latest version file moved to:", destination) Must be run in folder with decoded bundles, it moves latest version files to Assets subfolder. Then you can move this folder to main game folder "G_2.0.2_apkcombo\assets\bin\Data\" and load game folder to AssetStudioModGUI (took 16+ Gb of RAM): Model export works fine, with animations: Files with names starting with "r" is not encrypted or encrypted using more secure algorithms - no luck here.

So just looking at what you've posted and written, can't look in depth at the moment... -Model separation might be okay. Sometimes you do get some funny separation going on and it's not always readily sensible -UVs might be correct, worth checking it against the actual game. But if by comparison to the game they seem wrong, I'd say to look at messing with how they're being read. It looks a little based on that last image of the turret texture overlay like UV scale might be slightly off, causing things to stretch a tad out of bounds. If the UVs aren't just floating point values I'd definitely play with that with a screenshot from ingame onhand. Cool stuff though, wishing you luck.

iirc, I think it uses python 3.6 and higher to run. All I gotta do is run the tool, and a window will pop up.

How do I run wwiser? I'm having trouble as I don't usually run python applications and I got a pyz and db3 file from the github.

So now the npk have a newer encryption，There seems to be no perfect solution at the moment。So sadly。

looks like ur tool doesn't grab the internal filenames for each voice like wwiser does

umm..... idk why but these bones are so messed up, maybe I'm doing something wrong, can anyone help

Using hex2obj:

Worked like a charm, thank you!

can someone help me with Real Racing 2 car models? iirc this mobile racing game from 2010 probably using Mint3D engine for the file format. PVR Textures were readable with pvrtextool so I don't think I need help with. Sample M3D model Fun fact: You might be thinking Firemint is related to Firemonkeys studio, yes these are the same dev studio before being bought out and merged with IronMonkey by EA. Camaro GS M3G samples.7z

Best choice is to use a python tool called "wwiser" Use that to load the bnk files, make sure to include the init.bnk file along with the chara voice .bnk files, and it'll spit out txtp files that's connected to the .wem files in the media folder. Use foobar with vgmstream plugin to convert to wav or other formats.

I'm also interested, what's the process to do so? I recognized the bank files but I don't recall what to do with them.

Voice files are pretty easy to extract. I've already extracted all the English Voice files.

Hello, is anyone able to extract audio files from the game? Namely the JP voicelines

Yes

Progress has not been made at all. To begin with, I attempted dynamic analysis to avoid the communication error during the startup of the game. I explored using Frida and mitmproxy, but due to setup issues or outright failure, no results were achieved from these methods. For the time being, the strategy will be either creating a simplified offline version by modifying the APK’s communication functions or tracing the functions in the .so files to follow the decryption process of the assets. I will likely update this with additional attempts as I proceed.

Anybody has a unpack script for this game? How to extract game files please like you did?

Sure, I got to say that maybe it's me because I had to finished the script with AI. Don't know if AI stuff is allowed here and if it's not then I'll just delete it. Maybe you can figure things out with this. It loads tmd2 files and tact file if they are in the same folder and have the same name, so rename the tact file. bleach_rebirth_tmd2(WIP).rar

Hi guys im looking for some help to understand the files from the game mentioned on the title, the file that im attaching is a ball model the only thing i was able to tell was this 4 bytes magic(NUDP); uint size; //unknown data until offset 0x114 uint id1?; //some id that indicates if its vertex data? in some models is 0x01000103 or0 x01000105 uint unknown; uint vertexCount; 16 unknown bytes vertex data, 32 bytes per vertex (still unsure but most of those values looks like floats) uint or float unknown2; uint id2?; // depends on the model, in this case 0x010003030 uint fixed1; //always 0x20 uint fixed2; // always 0xffffff7f triangle data? any help would be appreciated!

It's good that you are making progress, other people can learn something if they want to.

https://www.vg-resource.com/thread-29836.html I've looked at the scripts from Tamsoft, but none of them help. Can you share the animation script that you uploaded to the video?

Thanks so much for sharing your findings about the obfuscated filenames and potential encoding/encryption – that's really valuable insight for the community! As a huge fan of Magia Record and the whole Madoka Magica series, I'm incredibly interested in exploring the raw game files themselves, even with the challenges you mentioned. I was wondering if you might still have those dumped raw asset files available? If so, would you perhaps be willing to share them? A link via Mega or Google Drive would be absolutely amazing, if that's convenient for you. No worries at all if you're unable to or prefer not to share them, I completely understand. Either way, thanks again for your efforts in looking into the game's files!

There was A LOT of discussion here that was not related to AC Shadows localization. As a moderator I couldn't allow that, so I've removed all off-topic posts. From now on please post only comments that are directly connected with translation work. Thank you. 🙂
