A GBA question about networking
 

Why isn't there a GBA to USB cable that allows you to connect to other GBA gamers over the internet? simular to this one, but is used for more than recharging. http://image.lik-sang.com/images//la...charger-sp.jpg


I would think that someone could write a driver for this device. I imagine that it would be simular to gamespy/xconnect. I'd love to play Advance wars against people over the internet.
