 ### Running the Emulator
 You can launch the emulator in two ways:
 1. **Direct Launch**: Simply double-click `gb_emulator.exe`. Once the window opens, you can drag and drop any `.gb` ROM file into the emulator window to start playing.
 2. **Command Line**: Run the executable and pass the ROM file path as an argument.
    ```bat
-   .\build\Debug\gb_emulator.exe "path/to/your/game.gb"
+   .\build\gb_emulator.exe "path/to/your/game.gb"
