Its the russians, version of NES/Famicom. But its not licensed by Nintendo, because Nintendo didn't have a patent on their stuff in Russia. Thus the Dendy was born.
Personally, I have always wanted a Dendy; because I love all things NES related.
Actually, its funny that all countries have their own version of the NES; except for the PAL: European NES which looks identical to ours; with the word "European Version" written on the front.
The Dendy is like NES attacked Famicom and this is their unholy child; it has removable controllers like NES, but the shape of a Famicom and the colors of a NES.
It uses 60 pin Famicom games, but with a 72 pin converter you can play NES games also?
