GreenCitrus is a homebrew project for the Nintendo 3DS, designed to mitigate the yellow tint often found on TN screens. The tool works by filling the TN screen with a white color at maximum brightness for an extended period.

• Detects screen type (TN or IPS) on New Nintendo 3DS systems.
• Displays static and dynamic information about the system's screen type, battery status, and adapter state.
• Allows users to select the screen to be de-yellowed (top or bottom).
• Provides a simple and user-friendly interface.

1. Screen Detection: GreenCitrus detects whether the device is a New Nintendo 3DS and identifies the type of screens (TN or IPS) installed.
2. De-Yellow'ing Process: By setting the TN screen to display white at maximum brightness for an extended duration (recommended between 6 hours to 24 hours), the yellow tint can be reduced or eliminated.
3. User Interaction: Users can interact with the tool using the D-pad to select which screen to de-yellow, and view relevant information such as battery percentage and adapter state.

1. Download the latest release of GreenCitrus from the Releases page.
2. Copy the .3dsx file to the /3ds/ directory on your 3DS SD card.
3. Launch the Homebrew Launcher on your 3DS and select GreenCitrus.

1. Start GreenCitrus from the Homebrew Launcher.
2. Follow the on-screen instructions to select the screen you want to de-yellow.
3. Allow the tool to run for the recommended duration (6 hours to 24 hours) to achieve the best results.
