Aaron writes – “idBoy is a piece of software for the Nintendo Game Boy Advance. With idBoy and a simple homebrew interface, the Game Boy Advance makes a dandy bunny. It has great battery life, has square-wave synthesis audio channels (among others) perfect for producing CW (morse code) tones, and has a link port perfect for controlling a radio. As far as I’m aware, idBoy represents the first such use of a Game Boy, or any Nintendo product for that matter.” [via] – Link.
