In the eighties and nineties in China, Russia and other countries it was possible to buy NES clone that would play pirated NES games. It was called Dendy. Obviously it didn't have the CIC chip.<p>Typical game cartridge contained multiple games (i.e., for example, Mario, Contra and Ninja Turtles could be on the same cartridge) and was quite inexpensive. I didn't realize for years that in US one game would cost 10 times more than 10 games one cartridge for Dendy. Ah, golden days of piracy.
