Please Note: The Game Boy Advance Link Cable should be used when playing Game Boy Advance multi-player games only. If you are using Game Boy Color or original Game Boy games or you are connecting to the Game Boy Printer, please follow the hookup instructions using the standard Universal Link Cable.

Multi-Player gaming can be done using one of two methods on your Game Boy Advance or Game Boy Advance SP, depending on how the game was designed by programmers:

  • Method 1: All players must have a copy of the same Game Boy Advance game.
  • Method 2: Only one game pak, inserted into the Player 1 system, is needed. This option is unique to Game Boy Advance games specifically programmed to use this feature.
  • Method 3: Using the Game Boy Advance Wireless Adapter. Games must be specifically programmed to use this feature.
