Can someone tell me which button I'm supposed to press?

I'm playing MegaMan 64 and when I get to the first door it tell me to push this little yellow triangle button. I've tried pressing all the buttons that I mapped in 1964 but none of them worked. Here's a screenshot if it helps.

That's sad... have you never actually played a real N64?

Anyway, the button is C-down. It's not really a triangle, it's a down arrow.

Yes I know, sad isn't it? I've owned a 2600, NES, GB and SNES. Pretty much stopped at SNES. I had a friend with an N64 but I didn't get to play as much as I wanted to. Thanks for answering my question.
