"Genshin Impact" PC version updater, written in Python

Script, that allow to bypass original Genshin impact launcher patching process, in case when you playing on unsupported platform, like macOS or Linux, or you just don't like endless list of electron app on your pc. Allows manually specify the path to unpacked patch archive, even when patch folder on another drive.

Python 3.11.0 or higher
Download main.py from repo
Unzipped patch files.
hpatchz execution file. You can find files on their GitHub releases page.

Make sure, that you have enough free space for patched game, because script can't do it.

• Where you can download patch zip? You can download zip's manually from mihoyo servers, just google "direct download links for genshin impact".
  When you will downloading patch's zip's, pay attention to version. Mihoyo writes version in zip file name, like "game_4.0.0_4.1.0_hdiff", where 4.0.0 is version, that you have on your device and 4.1.0 is version, which will be the result of patching process. Usually, they provide for downloading 2 version below. Example: current version 4.3.0 - mihoyo api will provide "game_4.2.0_4.3.0_hdiff" and "game_4.1.0_4.3.0_hdiff", so you can update to current version from 4.2.0 and 4.1.0 etc.

• What is hpatchz? This is same program, that mihoyo used in genshin to create audio banks file (and in another products, probably), but they pre-compiled it in there execution, so we can't use from game dir.
  

• Where i need to place unzipped patch files? Where you want. I tested it by putting it on an external drive, works flawless. I don't recommend use network folders on Windows, macOS and Linux users can try, but i'm not tested it.
  

• Where i can find, what version of game installed right now? In "Genshin impact game" folder you have config.ini file (open it by text editing tool), that contain game_version= line, where number after = is version of your game. If you want start game with launcher, you need to edit this number, after patching process, otherwise game launcher will try to update your game

Pay attention, audio path must match with selected language, otherwise it will cause data corruption. Audio patch's will be called by different names: English audio patch will starts by "en-us_", Chinese - "zh-cn_", Japanese - "ja-jp_", Korean - "ko-kr_".
