Yes, in what particular regard do you think a port of Donkey Kong Land 1, 2, or 3 would be superior to that "terrible Chinese pirate port"?
I guess the graphics kind of flicker a lot, but that's mainly because there are so many sprites on screen at the same time. If you restricted the screen to the resolution of the Game Boy, there would probably be much less flicker – and you'd be playing on a tiny fraction of the size of your TV screen.
