• 1). Insert the game. Certain games require each console to have its own copy of the game, while others only need a single game cartridge in one of the Game Boys. Read the game's manual to see how many copies of the game are needed to play multiplayer.
  
  
• 2). Link the two Game Boys using the Game Boy Link Cable. Note that more advanced versions of the Game Boy (such as the Micro and Advance) allow up to four players to be connected.
  
  
• 3). Turn on the Game Boys (it's important not to turn on the Game Boys until this point in the process, or they will not be connected). The menu screen of the game you are playing will now offer a multiplayer option that both Game Boys must choose.
