"A GameBoy, GameBoy Pocket, or GameBoy Color has software available with
the ability to turn your GameBoy into a RedBox (Toll Fraud Device) This
software has been around for a while. These GUI based applications allow
you use you GameBoy to make free long distance calls, crack answering
machine passwords, and just use it as a tone dialer. Well the new
GameBoy Color has an interesting feature, an IR port. As mentioned on
HNN and elsewhere a few months ago there are vehicles that use IR as a
locking mechanism. With currently available software you can now teach
your GameBoy various IR codes including those to unlock vehicles.
Wondering how you get these programs into your GameBoy? Well, Nintendo
recently lost the court case against the person making and selling
GameBoy ROMS which makes it real easy to transfer files around. Another
example of how it is not the tool that is malicious but the user. "
