Because He Could: Atari 2600 in a Sega Game Gear shell

Here's something you've never seen before: a Sega Game Gear that can run for eight hours on just two AA batteries. Mind you it's because there's no Game Gear inside, but instead the innards of an Atari 2600 that outputs to a tiny 2.5-inch LCD screen.

It's the work of one Chris Koopa, a man driven mad by a lifetime of Nintendo jibes from his peers who has vowed to create a portable game golem from the bodies of fallen foes that will finally best the DS.
