[NOTE][NO games can be inside of your Device during this time!!] Insert the Wireless Adapter into EXT.1. Activate your Gameboy Advance system. The screen will show up and say "Gameboy". Wait until the Gameboy logo shines. "Nintendo" Should appear red, and Change to yellow and back, etc. You will then be prompted to select English or another language. I do not know what the language is, but it appears to be Asian in origin. If you are not... well, whatever that language is, select English. The Gameboy should then begin searching for another Gameboy with a properly inserted Wireless Adapter system. My knowledge of this extends to this point, but no farther.
