GameShark You can use a Game Shark cheating device in order to receive unlimited rare candies in your PC. First you will need to insert the GameShark into your Game Boy Advance and then insert your copy of 'Pokemon FireRed' into the GameShark. Turn the Game Boy Advance on and enter '44' at the GameShark code screen. Press 'Start' to begin the game normally. Travel to the nearest Pokemon Center and check the PC.
Go to 'My PC' and you will have an infinite number of rare candies. Although the number of rare candies may be gibberish like 'x8B9,' you can take out as many as you wish and never run out. Action Replay An Action Replay device is similar to a GameShark but is made by a different company. The process and idea is the same, although the code is different. Place the Action Replay device into the Nintendo Game Boy Advance and place your copy of 'FireRed' into the Action Replay.
