You might just want to wait for the Revolution to come out, I’m pretty sure it will be able to play gamecube games (in which case you’ll just have to find the games, like Wind Waker and the Metroid games).
If you get out at Zhongshan Middle School MRT, head north, hang a left at the next major intersection, and go straight ahead a couple of hundred meters it’s on the left side of the road. If you look across from the opposite side of the road the big Nintendo logo’s pretty easy to spot. It’s also Nintendo’s local representative HQ, IIRC.
