VortexTricks: GNU Vegas

Automate Vortex Mod Manager setup in Linux for Steam & Heroic

VortexTricks is a lightweight, self‑contained Python utility that

• Detects your Steam and Heroic installations
• Resolves duplicate titles between your Steam and GOG libraries
• Creates the necessary WINE prefix(es)
• Registers the games inside Vortex by adding the correct registry keys and creating save‑game / AppData symlinks
• Downloads and installs the latest Vortex release

Features

Feature	Description
Store detection	Automatically locates Steam and Heroic (GOG) installations.
Duplicate handling	Prompts you to decide which copy to keep or to use separate bottles.
Bottle creation	Creates a default Vortex bottle, or separate ones per store, with the appropriate WINE runner.
Registry registration	Adds the required Windows registry entries for each game into the Vortex prefix.
Symlink creation	Links the Proton prefix’s My Games & AppData folders into the Vortex WINE prefix so that saves and settings stay in sync.
Automatic Vortex install	Downloads the latest Vortex installer from GitHub and installs it into the chosen prefix.

Prerequisites

Software

Item	Requirement	Notes
Linux	Any	Tested with Fedora Linux 43 and 44
Python	3.9+	Tested with 3.14
Bottles	Required	Required for running Windows binaries
Flatpak	Required	Required for Bottles
Steam	Optional	Required for Steam games
Heroic Games Launcher	Optional	Required for GOG games
Proton-GE or Proton-CachyOS	Recommended	Includes protonfixes to enable script extenders
protontricks	pip package	Used to find Steam
requests	pip package	For downloading the Vortex installer
jsonschema	pip package	For validating gameinfo.json

Game initialization

Any game to be modded needs to be ran once before attempting to mod it. Otherwise, missing files may cause errors in Vortex. If you forget to add one of your games or install a new game later, you can just re-run vortextricks.py after initializing the new game.

Installation

# Clone the repo
git clone https://github.com/gsquarediv/vortextricks.git
cd vortextricks

# Create a virtual environment (recommended)
python -m venv venv
source venv/bin/activate

# Install dependencies
python -m pip install -r requirements.txt

---

Usage

source venv/bin/activate # if not already activated
./vortextricks.py

⚠️ Reboot before launching Vortex

Upon execution, this script will:

1. Detect Steam and GOG game libraries.
2. Prompt you if the same title appears in both libraries.
3. Ask whether to use the Steam copy, the GOG copy, or keep both in separate bottles.
4. Create the necessary bottles or WINE prefixes.
5. Register Windows registry entries for each game to enable auto-detection of the game path in Vortex.
6. Create symlinks for My Games & AppData.
7. Download and install Vortex if not present.

Command‑Line Options

At the moment the script has no command‑line arguments.

Manual Post‑Execution Steps

After the script finishes, you may need to perform a few manual steps to complete the setup:

• Mod staging folder
  Vortex needs a staging folder where it temporarily stores mods before deploying them. When running Vortex in Bottles (Flatpak), the default suggestions seem to work pretty well. You may be able to simply enable "Automatically use suggested path for staging folder" in Settings and let Vortex handle it. If that does not work, you will have to manually set your staging folder.

Extending the Game Registry

The registry of known games is stored in gameinfo.json.
To add a new game:

1. Add an entry in the array, e.g.:

{
  "name": "Example Game",
  "game_id": "examplegame",
  "steamapp_ids": ["123456"],
  "gog_id": "987654321",
  "ms_id": null,
  "epic_id": null,
  "registry_entries": {
    "HKEY_LOCAL_MACHINE\\Software\\ExampleCompany\\ExampleGame": "Installed Path"
  },
  "override_mygames": "ExampleGame",
  "override_appdata": "ExampleGame"
}

2. Validate the JSON against the schema:

python -c "import jsonschema, json, pathlib; schema = json.load(open('gameinfo.schema.json')); validator = jsonschema.Draft202012Validator(schema); json.load(open('gameinfo.json'))" || echo "Invalid JSON"

3. Rerun the script – the new game will now be recognized.

Tip – The registry_entries dictionary key is the full registry path; the value is the name of the key. vortextricks.py will insert the game path as the value of the key.

Troubleshooting

Symptom	Cause	Fix
ModuleNotFoundError	Virtual environment not active or requirements not installed	See Installation
RuntimeError: Could not locate bottles-cli	Prerequisites not installed.	Install Bottles via flatpak install com.usebottles.bottles
Duplicate game prompts not showing	The duplicate detection logic didn’t find overlapping game IDs	Ensure both game IDs are in gameinfo.json
Vortex UI is not scaled properly	Your desktop environment has implemented user interface scaling in a retarded way	Try running Vortex with --force-device-scale-factor=2
Vortex window does not render properly	OpenGL errors	Try any of the following: __EGL_VENDOR_LIBRARY_FILENAMES=/usr/share/glvnd/egl_vendor.d/10_nvidia.json (Nvidia only) Set Renderer to GDI in Bottles winetricks renderer=gdi Vortex.exe --disable-gpu
fallout.ini keeps getting reset when launching the game	FalloutNVLauncher.exe is being launched instead of nvse_loader.exe	Use Proton-GE or Proton-CachyOS OR use the following launch option with Valve Proton: bash -c "DO=(%command%); \"\${DO[@]/%FalloutNVLauncher.exe/nvse_loader.exe}\"" Note: Proton-GE 11-1, Proton-CachyOS 11.0-20260602 or older need the following additional step for Fallout: New Vegas: mkdir -p ~/.config/protonfixes/localfixes && curl -fsSL -o ~/.config/protonfixes/localfixes/22380.py https://raw.githubusercontent.com/Open-Wine-Components/umu-protonfixes/refs/heads/master/gamefixes-steam/22330.py && chmod +x ~/.config/protonfixes/localfixes/22380.py
