Can anyone possibly help?

I want to browse stuff with my NDS lite on the internet, and I notice I should insert memory expansion in the gba slot. Can I buy that alone without the game card? Or can supercard and M3 lite help?

Why not try the Nintendo DS Browser made by Opera? So far this is the only official web browser for the DS. Other than that I do not know of any other options.

That's the one he wants to use, but yes you'll either have to buy the memory expansion or use a slot 2 card to act as memory. Alternatively you can also try some of the homebrew browsers.

yet I am in Hong Kong ... where to buy the stuff?
