Game installation and updating

Pick an application from the list below that suits your preferences. Each of them is capable of installing and updating the game. Additional features such as automated patching might or might not be included.

• The official launcher
  • Note: Wine 8.7 or newer should be used to avoid a memory leak in winedevice.exe
  • See INSTALLATION.md for further instructions.
• Paimon Launcher
• An Anime Game Launcher
• Yet another anime game launcher (macOS)
• update_gi.sh (CLI only, described below)

Updater implementation in Bash

This section documents the script update_gi.sh. The other scripts located in this directory have a short explanation in their file content.

The following steps are automated:

1. Check for game updates
2. Download the game files
3. Revert any previously applied patches
4. Install or update the game files
5. Apply the newest patch

Requirements

This script requires following applications:

• bash (update and patch script)
• jq (JSON parsing)
• Either aria2c, wget, curl or axel (file download)
• xdelta3 (patch script)

Usage instructions

The current working directory (pwd) specifies the update or installation path.

Example + syntax:

cd "/path/to/game/directory/"
bash "/path/to/dawn/updater/update_gi.sh" [OPTIONS ...]

List of OPTIONS:

• --help: Shows a short help text
• install: Switches from the "update" to "installation" mode
  • By default, an update will be performed in the current directory
• nodelete: Keeps the downloaded archives after the installation or update.
• predownload: Checks and downloads pre-download-game archives
  • To perform the update afterwards, re-run the update script without the predownload option.

If errors occur after updating the game files, re-run the patch scripts manually.

New installation

Use the install command line option to install the newest game version to an empty directory.

Example:

# Create a new directory in HOME (~) for the installation
mkdir -p "$HOME/Genshin Impact Game"
cd "$HOME/Genshin Impact Game/"

bash "/path/to/dawn/updater/update_gi.sh" install

Game update

Updates the game in the working directory to the newest version.

Important: If the official launcher was used for the installation, ensure that the current working directory (pwd) contains GenshinImpact.exe but not launcher.exe.

Example:

# Update game located in HOME
cd "$HOME/Genshin Impact Game/"
bash "/path/to/dawn/updater/update_gi.sh"

For advanced users: perform_update.sh can be used to manually apply downloaded archives
