I get an error with the 56.6 patch whether I use the english version or not; I'm following the install guide and decrypting while setting the system file to false for sensing decryption. Does anyone have a full install or have figured out how to make it work?
What decryption method are you using?
One of the image folders, I think was called Pictures needs to be broken down into 3 parts if you're using that online tool. It's too big to be handled in one go.
Check the file count and make sure it's the same between original and decrypted folder.
Maybe you can use some kind of file deduplication tool that will scan the game folders and find identical files (including those with different names) then convert the dupes into symbolic links towards the first copy.
