Nintendo 64 games and controllers

I’m a 64 fanatic, and can’t find games or controllers anywhere. English or Japanese are ok. I’m specifically looking for mariokart 64, but any games would be welcome.

You can find emulators online, if you don’t mind playing on your pc.

In the Taipei city mall, there are more than a few video game stores that sell 64 games and consoles. I’m not sure about the prices, but I have seen them many times. The city mall is underneath the Taipei Main Station building, just in case.
