Journal for 1.0.1

Service

The mhyprot2.sys service is started in UnityPlayer.dll.

0x90 @ POL:

[...] i applied the patches directly in-memory (in the running process) and even got around the checks directly in x64dbg with the help of breakpoints and scripts.

So either it's a memory hash, or has directly something to do with the mhyprot2 service not running.

There were no UnityPlayer.dll after 1.0.1 (when 31-4302 re-appeared), hence this is probably sent to the server for verification.

"Persistent" data changes

timbuntu @ POL:

So that's the files that changed since it was working as far as I can see: (expiring link)

Assuming the old game data is correct, there weren't any content changes, hence being unrelated to error 31-4302.

Network

Clean logs provided by SeppNel.

Detailed information: network.md

A large majority of packets has the same length when comparing Windows and Linux.
Game data is transferred using UDP, security stuff seems to be done using TLSv1.2.
The Linux client begins loading the game data over UDP, but opens a connection to the logging server to report the error.

Note: UnityPlayer.dll did not change in the update that arised the error message (again)! This either means the server disabled some checks, or the verification is done using server-sent scripts (Lua?).

Function name source: global-metadata.dat

Some lines may originate from UserAssembly.dll, but the debug names from global-metadata.dat must first be assigned to addresses to confirm this.

Lua injection

How to apply the modification:

cd "/path/to/Genshin Impact Game"
bash "/path/to/GI-on-Linux/101/lua_injection.sh"

.. and run the game from that working directory.

The script will create a symlink. Copy the file to ensure that it'll work properly on Windows.

Results (outdated): https://pastebin.com/raw/ciay6HXj

"sc stop mhyprot2" is run after initialising Lua. The Anticheat check is performed before showing the login screen.

Warning: This code leaks information about GI's internals that are unrelated to this project.
