Hi there @190nm!
This is a long shot, I'm currently working on reverse engineering Nier Reincarnation in an attempt to make an offline version for PC.
I've ran into a bit of a roadblock when it comes to decrypting the assets, I understand that octocacheevai is required but as the original servers are no longer available I have no way to acquire it.
I was wondering if you still had access to this, or any of the decrypted assets? It would be a huge help. Thanks!
