Game Boy Advance SP - Troubleshooting - Game Won't Start

If you can not get your game to start, or you can not get past the boot-up screen that reads "Game Boy," the most common reason this occurs is that the Game Pak is not fully inserted. Turn off the Game Boy Advance SP, firmly insert the Game Pak until it clicks, and then turn the system back on.
