Posted on BenHeck.com, home to all things homebrew, was a creation by some clever fellow named Marshall. Seems he thought it would be a good idea to make a handheld that could play full SNES cartridges.

Looks like it's about the size of a Game Gear and sucks down batteries even faster (6 AAs in about 2 hours), but that's the price you pay for having "Super Metroid" in your pock..um...napsack.
