Instructions

1. Download and run the latest release installer.
2. Follow the installer prompts — it will create start menu entries and desktop shortcuts.
3. Generate your identity file (see instructions below).
4. Go to Options > Settings and select your identity file.
5. Go to Options > Settings and select your NostaleClientX.exe.
6. Add a Gameforge account.
7. Select the accounts you want to open and click Play.

How to generate identity file

You need to extract a valid blackbox from a request to auth/iovation. The easiest way is to use BlackboxExtractor.exe, which is bundled in the installation directory:

1. The official Gameforge client can be running already — BlackboxExtractor will attach to it. If it's not running, BlackboxExtractor will launch it automatically.
2. Run BlackboxExtractor.exe from the installation folder (default: C:\Program Files\Gfless Client).
3. It will automatically launch the Gameforge client and capture the blackbox from the auth/iovation request.
4. The blackbox string is copied to your clipboard automatically. You should see it in the console output.
5. In GflessClient, go to Options > Identity generator, paste the blackbox, and click Generate and save.
6. Save the generated identity JSON file to a location of your choice.

Note: If you prefer to capture the blackbox manually with Fiddler, you can still do so — but the bundled BlackboxExtractor is the recommended method.
