When using Knulli OS on Anbernic retro handhelds like the RG40XXV, many features feel streamlined and console like but not everything is clearly explained on screen. One of the most commonly missed features is favoriting games, simply because Knulli doesn’t show any button hints or menu instructions for it. If you’ve ever wondered how other users mark their go-to games with a star or keep their best titles easy to find, this guide walks you through the exact (and surprisingly simple) method.

Step-by-Step: How to Favorite a Game in Knulli OS
This method works across systems and game lists.
- Navigate to any game list
- Highlight the game you want to favorite
- Press and hold the X button for about 2 seconds
- Release the button
That’s it, you’ll immediately notice a star icon (★) appear before the game title, marking it as a favorite; repeat the same action and hold X again for two seconds to remove it.
How to Show Favorite Games at the Top (Advanced Tip)
By default, favorited games don’t always appear at the top. You can change this behavior.
- From a game list, press SELECT to open View Options
- Scroll down to View Customization
- Find “Show Favorites on Top”
- Change the setting from Auto to YES
- Exit the menu
Once enabled, favorited games will always appear above non-favorites, giving you instant access to your best titles, especially useful if you only favorite a few games per system.
Tips and Best Practices
- Favorite only your top games to keep lists clean
- Use favorites instead of creating duplicate ROM folders
- Combine favorites with per-system filtering for faster navigation
- Great for demo units or lending your device to friends
Once you know this shortcut, favoriting becomes second nature—and it dramatically improves daily use on Knulli-powered Anbernic handhelds.
