I rip some data from SWORD ART ONLINE Alicization Lycoris. The file header is CRILAYLA but using CPK`s DecompressCRILAYLA cannot decompress

Where is the key to the archive to download?

@lisomn: It works exactly the same as for SAO: Hollow Realization. Use YACpkTool to unpack cpk and corresponding scripts for OFS3 containers and models/text/etc.

I updated the link, can you check the file, the link you attached does not seem to have more help with CRILAYLA, I have tried these

@lisomn: I believe only headers are additionally obfuscated (not even for every files), the rest seems fine to me, look at the examples below. You can download other games on PhyreEngine and take a look how those headers should look like for models or textures. Sorry, I'm not interested in the game, just passing by.

Actually, if you'll use lame solution like extracting compressed assets "as is", unxor first 22 bytes with 0xFF, repack it back to cpk and extract with any actual cpk tool (like YACpkTool or CriPakTools fork by wmltogether), then open and unxor E0 1C bytes (specific for this example) in uncompressed asset again, it will work.

Here is an example, where _uncompressed_unxored part is compatible with SAO Hollow Realization tool (viewer / exporter), linked above.

Maybe you should initially unxor -1 byte to avoid the second fix, didn't test it.

Thank you very much for your tool, but I don't know if it's the version problem, Error occurred in data.cpk\chr\mod\10001 (I'm very sorry for my English. It comes from translation software)

I found this problem, it may be in the xor part. I don't have a lot of testing, you can try to analyze youself:geek:
2 bytes from 0x16 to 0x17 require manual 0xff XOR

Is your DecompressCRILAYLA method from one of these two? I spent the night trying to figure out how to decrypt it, my stupid brain

Hello, help me figure out the cpk packing. Found the reason for the crashes (in the Russian version). Unpacked cpk using Console version CRI Packed File Maker. But the game does not want to load the file packed back - crashes on startup. I'm in Steam dim128128- add as a friend, maybe we will quickly figure out the work of cpk.

https://yadi.sk/d/b1TqmMEfV6ciJg ( here is the file I created and exported from the developers (a lot of unnecessary information, due to the fact that the console version of the program does not export correctly).
But here it is view that they do not have groups (none), an attribute is assigned to all files (ENC) (but I don't know what they contributed to it). And all files except two are compressed. ID numbers are also assigned by me as they have. But the game still crashes(

This is how cpk was created by the developers

UPD

Here is the second version (complete, here is the creation of the csv file). Differences from the developer version that I noticed:
Enable file name info (4600 0 bytes) [sorted]- in develop file
Enable file name info (4584 0 bytes) [sorted]- in my file

Develop file size - 333 532 bytes
My file size - 333 534 bytes

Whether this is the reason for the crash or how to fix it I don't know. The main question is what to add an attribute to the ENC (the video shows that the developers have it enabled, but I don't see its contents, so I left it blank for myself).
