My Boy! Lite is a free emulator for Android devices that allows you to play classic Gameboy and Gameboy Advance games on your mobile phone or tablet. It's a great way to relive the nostalgia of your favourite childhood games, without having to carry around an old and bulky console.

To start using My Boy! Lite, you'll need to download the app from the Google Play Store. Once you've installed it, you can then search for and download ROMs of the games you want to play. ROMs are essentially the game files, and you can find them on various websites online.

When you open My Boy! Lite, you'll see a simple and straightforward interface. You can use the File Selector to find and load your ROMs. You can also use the settings menu to change various aspects of the emulator, such as the button layout or the graphics settings.

One of the best features of My Boy! Lite is its support for save states. This means you can save and load your progress at any point in the game, allowing you to pick up where you left off even if you don't have time to play for a long period of time. You can also use cheats and adjust the speed of the game if you want to make things easier or quicker.
