Question About Pokemon Snap!

[Colbz]

I got pokemon snap working.. but I can't play it..
I'm new to all this, and I don't know what I'm doing. Am I supposed to be using my computer keys? Or do I use something else?
My enter button works as a 'start' but nothing else works. I'm confused.
Please help!

If you are using PJ64, X = A, Z = Z, C=B, A = Left Trig., S = Right Trig. The Joystick are the Arrow Keys, and the C Buttons are Home, Pg Up, Pg Down, Ect.
