Explanation

mhyprot2.sys is a kernel service which is and will not be supported by wine. The service is used as cheat detection, hence being well protected.

Possible solutions:

• Patch out anticheat (reason why this project exists)
• Support the kernel service support in Wine
• Wait for an official Linux build
• Wait for Blue Protocol as an alternative (2021/22)

1 Week of Gameplay

From 23 October 2020 (1.0.1 update) to 28 October 2020 the game was confirmed working on multiple Wine versions (5.17 and newer). Prior and after, the error code 31-4302 is shown.

What has changed? Probably a server update. Needs investigating.

Project rules

1. The workarounds must not be used for cheating. GI is a nice game and does not deserve cheaters.
2. miHoYo reserves the right to distribute files. Please do not share any game data in public.
3. Beware that logs may contain personal information, such as MAC addresses or login data.

Applying the workaround

Apply the patch(.sh) as follows:

cd "/path/to/Genshin Impact Game"
bash "/path/to/GI-on-Linux/GAMEVER/patch.sh"

A backup will be created and the relevant files patched.
