Pause loading:
Press Start + Select at the introduction screen after the first sound (swoosh). The Nintendo logo should disappear as it makes the Mario pause sound, and the system will pause (lock). Then press any button after the second sound (ping) to bring back the Nintendo logo with another sound, and the game will continue to load. Note: This only works for Game Boy Advance games.

Wireless Adapter: Use with games that have multi-player with only one cartridge:
Some games such as the Classic NES series will allow multi-player games using only one game cartridge that can be shared with multiple Game Boy Advances. To use this feature with the Wireless Adapter, press L or R on the Game Boy Advance with the game and adapter. Select "Linked Play" from the menu that appears. The wireless connection options should appear. Select "1P" from the menu. The Wireless Adapter will enter transmission mode and wait for a connection from any other Game Boy Advance with a Wireless Adapter. Power on any other Game Boy Advance with a Wireless Adapter (but no game cartridge). A menu that will allow you to select the game that is being shared will appear. Choose the title and that game will be transmitted from the other Game Boy Advance. The Game Boy Advance without a cartridge can also continue playing the game in single player mode after the wireless connection is canceled.

Wireless Adapter: Chat:
Turn on the Game Boy Advance with only the Wireless Adapter inserted, with no game. A menu with "English" or "Japanese" options will appear. Select "English" and you will be able to make chat rooms and chat.
