The Sega Master System with Built-In Game Gear Cart Slot

So, how would you like to be able to play your Sega Game Gear games using your Sega Master System?  Well, looks like you're not the only one as someone has decided to mod their Master System by adding a cart slot to play Game Gear games!  That someone is Eric Bishop, who has even modded the controller to include a Start button.  Check out the video below to see the system in action...
