### Standard & Lightning modes

!!! warning "Lightning mode requires a 120hz capable monitor."

!!! tip ""

	To make use of the Lightning Mode, which unlocks the subscreen and 120FPS, we need to go to the `contents\prop` folder and edit the `ea3-config.xml` file.

    We're interested in these lines:

	```xml
		<soft>
			<model __type="str">LDJ</model>
			<dest __type="str">J</dest>
			<spec __type="str">E</spec>
			<rev __type="str">A</rev>
			<ext __type="str">2024050700</ext>
		</soft>
	```

    This is the line that determines if the game will run in Standard (60 FPS) or Lightning (120 FPS) mode.

    ```xml
	<spec __type="str">E</spec>
    ```

    - ^^`E`^^ for Standard (LDJ-012, LDJ, 60hz)
    - ^^`D`^^ for Lightning (LDJ-010, TDJ, 120hz)
