i think Waixing is still selling its old famicom games but they aren't developing any new ones as far as I know. Same goes for Nanjing. I don't know of any company developing new Famicom games to release on cart (maybe some obscure company in China is still doing it though, who knows - no one had heard of Nanjing until about 2008) but Nice Code might still be making them for plug & play consoles.
