The GameShark cheat device for the Game Boy Advanced allows you do adjust game settings, receive items and access multiple levels. In "Pokemon FireRed," you can use the GameShark device to access a Walk Through Walls cheat that gets you through buildings, rocks and other obstacles. The same process also works with the Codebreaker cheat device.
Game Shark Setup
Power off your Game Boy Advanced before starting. Remove any game cartridge and insert your "GameShark" cartridge. Insert the "Pokemon FireRed" cartridge into the top slot of the GameShark cheat device. Power on the Game Boy Advanced and wait for the GameShark menu to load and recognize the game you have inserted. If the cartridge cannot recognize the game, go to the "Game List," press "A" and scroll down until you find it.
To use the Walk Through Walls code, enter a master code that gives the GameShark access to the game's cheat system. Press "A" on the "Master Code" entry. Enter "000014D1 000A 10044EC8 0007" for the "Master Code" and press "A" on the "ON" to activate the code.
Press "A" on the "New Code" icon and use the onscreen keyboard to type in "Walk Through Walls" for the code title. Enter the code "509197D3 542975F4 78DA95DF 44018CB4." Press "A" to confirm the code entry and activate the cheat.
Press "B" to return to the main menu. Go to the "Apply Codes and Start Game" option. The GameShark automatically processes the codes and launches the game. Start a new game or load your saved game file. Walk around with your character. When he approaches a wall or object, he will automatically shoot through it. When you play the game without the GameShark, the code will not be activated.
