v2.0

🛠️ Version 2.0 – Major Update

🎯 Highlights

• Removed dependency on Protontricks
  The launcher now uses its own implementation for game launching — no external dependencies required anymore!

• Initial Setup Window Removed
  No more need to install or keep Spacewar — clean first launch experience.

• Per-Game Prefixes
  Every game now uses its own isolated Wine/Proton prefix.

• Proton Version Selection
  Choose the Proton version to use for each game individually.

🧰 Features & Improvements

• UI Redesign
  A refreshed, cleaner, and more intuitive user interface.

• Game Time Tracking
  Keep track of how long you've played each game.

• Steam Runtime & Overlay Support
  Support for Steam Runtime and Overlay (may not work in all cases).

• Complete Game Removal
  Option to fully delete a game and all associated data from within the launcher.

• Advanced Launch Arguments
  Add arguments support before and after the executable.
  Preset templates are available for:

  • mangohud
  • gamemode
  • gamescope

• Open Game or Prefix Directory
  Access game or prefix folders directly from the launcher UI.

• "About" Window
  Displays the launcher version along with links to GitHub and Telegram.

🧩 Compatibility & Migration

• Save Migration for Older Versions
  Temporary code added to migrate save data from older launcher versions to the new per-game prefix structure.

🐞 Fixes

• Fixed mangohud Support
  Improved compatibility and functionality.

• Fixed Environment Variable Handling
  Environment variables are now correctly passed to game processes.

• Improved Debug Logging
  Game name and parameters now appear correctly; also includes /etc/os-release info.

• Optimized 7zip Execution Checks
  Removed global chmod +x call — permissions now checked at runtime only.

• Removed Steam Workaround
  The legacy workaround for "Steam is not running" has been removed — it’s no longer needed.

🔧 Other Changes

• Various small bug fixes and improvements.

chmod +x onlinefix_launcher_installer && ./onlinefix_launcher_installer

v1.5

💫 What's new

• The launcher now runs games with WINEDEBUG disabled by default, and redirects the game's output to /dev/null (essentially disabling it). This fixes issues with games that spam the log, causing the launcher and the game to freeze.

• A separate option has been added to the launcher to run games with debugging enabled for troubleshooting purposes.

• The constant warning about enabling GameMode has been fixed — it now only appears if you actually enable it.

---

▶️ To run, make the installer file executable.

chmod +x onlinefix_launcher_installer && ./onlinefix_launcher_installer

📦 The launcher requires mandatory additional dependencies. See here.

v1.4

💫 What's new

• Fixed compatibility with Ubuntu/Debian
  ‼️ To ensure the launcher works correctly on these distributions, protontricks must be installed using a new method. See the updated Protontricks installation section for these distributions in the README.

• Removed the trigger on exit code 1, as it was misleading for most users.

• Fake Steam is now automatically enabled if the game was downloaded from FreeTP.

• The log now shows not only Wine messages but also the game's own output.

• Disabled the ability to enable MangoHud until further fixes are implemented.

• Steam is now launched directly via /usr/bin/steam instead of xdg-open (avoids issues on Fedora 42).

• The behavior of Fake Steam has been changed — previously, it didn't always restore the Steam PID value in the registry, which caused games to break after applying FreeTP fixes.

📦 The launcher requires mandatory additional dependencies. See here.

v1.3

💫 What's new

• The launcher now forces Proton to use DXVK/VKD3D (since, for reasons unknown to me, WINED3D is used by default on some distributions without this, which is why the games did not work)
• 7zip is now shipped with the launcher and is not needed as a dependency (The build is taken from the Arch Linux repositories)
• Fixed the lack of English translation in some places

▶️ To run, make the installer file executable.

chmod +x onlinefix_launcher_installer && ./onlinefix_launcher_installer

📦 Dependencies

Before using the launcher, ensure that the following packages are installed:

• protontricks
• ffmpeg

Installing protontricks:

SteamOS / Steam Deck:

1. Disable the read-only mode for the file system:

   sudo steamos-readonly disable

2. Edit /etc/pacman.conf and set SigLevel = TrustAll
   • Warning: Using TrustAll disables package signature verification, which can pose security risks. However, without this change, pacman does not function properly on SteamOS.
   • You can use nemo or kate to edit the file:

     sudo nemo /etc/pacman.conf

     or

     sudo kate /etc/pacman.conf

3. Enable the Chaotic AUR repository by following the official instructions
4. Install the protontricks:

   sudo pacman -Sy protontricks-git

5. After installation, it is recommended to re-enable the read-only mode:

   sudo steamos-readonly enable

Ubuntu and derivatives:

sudo apt install protontricks

Fedora:

sudo dnf install protontricks

Arch Linux and derivatives:

If you do not have yay installed, first install it:

sudo pacman -S --noconfirm git
git clone https://aur.archlinux.org/yay-bin.git
cd yay-bin
makepkg -si
cd ..
rm -rf yay-bin

Then install protontricks using:

yay -S --noconfirm protontricks

Solus:

sudo eopkg install protontricks

v1.2

💫 What's new

• Added support for online fixes from freetp.org, including fixes that use Cube Racer (Steam Remote Play)
• Created a fake Steam (steam.c - source file, steam.exe - compiled) for fixes that get “Steam not running” error.
• gamemode is now enabled for each game separately, as it can cause problems with fixes.
• Added mangohud support
• Added editing environment variables separately for each game of the game (e.g. you can now use PROTON_USE_WINED3D=1)
• Added error catching and logging
• Since the Steam overlay is not available in games run through the Launcher, the Launcher now listens to pressing Shift + Tab and opens the Steam friends list (on Wayland may not work in all composers)
• Other minor fixes.
