Thirty years after its landmark 1989 release, Nintendo?s Game Boy and its long line of successors continue to capture the imagination of thousands of players who harbor a nostalgic attraction to the technologies of their youth. Montreal-based Retro Modding has developed a profitable business modifying (or ?modding?) old video game handhelds and selling them alongside tools and parts for do-it-yourself projects. These alterations combine today?s expectations for consumer electronics (like backlights and rechargeable batteries) with the iconic form factors of early handhelds.
