The hdmyboy is the creation of Zane Amiralis and Joshua de Haan. The project's Kickstarter page says that Josh hacked into a Game Boy so he could play it on an old PC monitor. "By tapping into the digital signal deep within the game boy, he could generate amazingly crisp graphics. After playing some Mario, Tetris and Zelda we decided we just had to share this and take it to the next step."
The team have spent 3 months building a prototype that allows for full HD support, so they thought they would see if other players would like to experience the same by turning to crowdfunding.
The hdmyboy supports 1080p full HD and also 720p too. You can play games on your TV in the same ratio as on the Game Boy, or even stretch it out to a full screen mode.
