The application is essentially a unity-gb emulator wrapper acting as a live wallpaper, which also includes many additional features and customization options, such as different layouts and an audio visualizer.
You can choose to either play the game yourself like you would on any regular emulator or record macros, essentially turning it into a nice animated backdrop. If you're worried about system resource utilization then don't be, as the emulator will automatically stop when you run full screen apps and games.
