So has anyone else seen one of these retro duo things? I bought mine a few weeks ago after scanning around the internet looking for a working nes to play my library of old games on when i stumbled across solidsignal.com. After checking out the specs i decided to go ahead and order one, and let me tell you, It works wonderfully! Even better then the original, and BONUS it can play old snes carts as well. I only had to blow into the cartridges one time to get the years of dust out of them after that they worked well, and the only downside is that you cannot actually use the old nes controllers like the light gun and such. The only controllers you can plug into it are snes ones, but you can use either the ones it comes with or your old ones (if you can find them  ) Just thought more people might like to know about this in case your in the same situation i was, aka a bunch of old games sitting around collecting dust that you'd like to play if only you had a working system!! Well now you can. Happy gaming.
