Don’t know what to do after you lost your 3DS AR card? Stop running around like a headless chicken and be a man about it – while saving some money in the process, of course. We’re talking about using a marker to make your very own AR card, which the 3DS will recognize anyways. Looks like the camera isn’t too hot on being precise, as anything hand drawn and is roughly similar to the original will do. Here’s a thought – how about scanning in all your AR cards before use, to make sure you always have a digital copy to print out just in case of an emergency?
