🔧 Technical Details

Installation Paths Checked

The program automatically searches these common locations:

• C:\Program Files (x86)\Steam\steamapps\common\Cyberpunk 2077\
• C:\Program Files\Steam\steamapps\common\Cyberpunk 2077\
• C:\Games\Cyberpunk 2077\
• D:\Games\Cyberpunk 2077\
• C:\GOG Games\Cyberpunk 2077\
• And more...

How It Works

1. Detection: Scans common installation paths for bindings.json
2. Reading: Parses the JSON file to extract the overlay key value
3. Conversion: Converts decimal values to hex, then to human-readable key names
4. Writing: Updates the JSON file with new key combinations when setting keys

File Location

Your CET overlay key is stored in:

<Cyberpunk 2077 Installation>\bin\x64\plugins\cyber_engine_tweaks\bindings.json
