Genshin Impact Private Server

[huuhait]

o/ hey all, Some good progress has been made by others (not my self IRL commitments); It is possible to login to the private server, but all you can do is explore, cant switch characters, use skill...etc. This is not the same as the dev/gm offline mode this is connecting to a private server. TLDR: Still in progress, can now login to a 100% private server.

for the client private server will it be updated monthly version? Or maybe every few months

Woah slow down a bit there , let us just wait and see if there an actual success with the beta launch first before jumping to post production. There has been tonnes of breakthrough but it is very much mid progress , Im far from knowing all this client-server stuff but if I were to guess based on the discussion on discord , it is about 30% , maybe 40% WIP.

am really looking forward for it to be complete

Is there a way to get in touch with people who have been working on it? I have reverse engineerd the private beta client and have written server logic for http request handling as well as identified the protocol, they are using enet for communication. I was able to dump the c# definitions, so it should be possible to recover serialized packet classes etc. I also looked into bypassing the mihoyo protection driver (mhyprot2) but not succesfull yet. Let me know if you are interested to work with me and I can share my progress with you. here is a snipped of functions and offsets for asm (cbt1 client):

Have you been able to do some follow up to this? We also recently cracked the xor packet decryption but are now kind of stuck with the sheer amount of traffic we need to analyze... We havent yet looked into the UserAssembly that deep to possibly decrypt the base64 data returned by the server maybe you can help there? Or is there anyone else here who has more insight?

any idea if me and two others could join in that discord? were sitting on reversing the 1.4 client atm and have found the xor key decryption. see post above :=)

[HardFeelD]

Hello everybody How are you doing with the server? When to wait for release?)

[wawxz2021]

Has anyone tried to check decompiled Android app file? I think that's a great idea! Correct me if I am not correct, because I am a green hand.

[TifaLockhart]

So,the discord for now its only reserved to who knows how to work on things,right?But if that is the case,how will we know when it's done?Will you guys give a link here after it's done?Considering it will take long anyway but yeah...i have those questions floating in my head from quite a while back when i started following this thread.

[dicktrace]

We are also looking forward to being able to help and make this project go forward

[Pizzabazinga]

It's been a few months since there was any update on this thread. Is this project still being worked on? I really hope it is.

[Zidax]

Yeah, I'm looking forward to this development too. Can't wait for the private files to be release. Any update?

[Ochi]

Is anyone willing to share the xor decryption algorithm? From what I see, it changes every session, but for a single session it is deterministic and reused for all packets (both server and client). Maybe a table or something? Some clues would also be helpful as to what data is used to initialize this table/sequence.

if you mean packet i know someone who get 1.4 and 2.0 packet decryption algorithm

[Ochi]

if you mean packet i know someone who get 1.4 and 2.0 packet decryption algorithm

Yes, I mean packet. Are they willing to share?

[pong]

Yes, I mean packet. Are they willing to share?

No they dont want me to share

[Ochi]

Does anyone have a link to "UnityPlayer.dll" from version 1.2? This is needed to decrypt the game files and will help with reversing.

EDIT:
You can download the official 1.2 client here
