Instructions
Insert your Gameshark cartridge into the Gameboy Color device. Make sure the Gameshark cartridge is securely inside the slot before inserting the game cartridge.
Plug your "Pokemon Yellow" game cartridge into the Gameshark cartridge and power on your Gameboy Color by sliding up the "Power" switch.
Scroll down the list of gameshark codes and find the folder labeled "Pokemon Yellow Version." If the folder is not there or the code you are looking for is not there, you can manually enter the code yourself in the textbox at the top of the menu.
Type in the code: 1xx73D1 (replace the "xx" with the unique code number). The code numbers can be found on the SuperCheats website,
