Instructions
Verify that your GameBoy Advance has a full charge, as you do not want the battery to run out during gameplay. Use your GameBoy Advance AC adapter and insert the plug into a wall socket and the other end into your GBA. When the light on the GBA is green, the unit is fully charged.
Insert the "Buu's Fury" cart in the back of the GameBoy Advance. The label will be facing outward as you slide the game in the cartridge slot. Slide the cart is far as it will go until it is securely placed in the GameBoy Advance.
Slide the "Power" switch, located on the side of your GameBoy Advance, to the "On" position. The game is displayed on the main screen.
