Retro Duo: Plays both NES and SNES games

Despite our huge collection of aging games consoles, when we saw the Retro Duo NES/SNES Game System on Think Geek, we were immediately intrigued.

Aside from playing both NES and SNES games, both cartridge slots are top-loading.

That means no more trial and error playing Legend of Zelda or Super Mario Brothers 3 -- no more taking the cartridge back out, blowing on it furiously, slamming it back in the console and powering up, hoping you're not greeted with a screen of wavy lines, only to once again take Mario's name in vain.

For $50 (£35), you get the system and two controllers. You can also use your old Nintendo controllers if you prefer. Unlike some legally dodgy retro systems we've seen, this console comes with no games on a chip or included cartridges. You use your old game cartridges.

As a supermegahellacool bonus, it also plays most Japanese import games, as well as UK cartridges.
