Although the project is still in the works, Markus Hirsch is working on a custom, infrared remote control for his Game Boy Advance for which he says there’s no standard remote control that works on it:
There are many universal remote controls out on the market. None of them have the features of a GameBoy Advance fittet with a little infrared transeiver and a functional program.
It features a grafical interface with customable buttons. The signal information can be sampled from the original remote control. One key feature is that it is possible to programm up to two commands on one button. So if your favorite TV staion is chanel ’13’ you can sample a ‘1’ and a ‘3’ on one button and A.I.R. will send both commands at once.
