If I didn't know any better I would have assumed this was a resistor, but it was on a PCB with the label of "C4" which leads me to believe it is a capacitor. This came from a Zelda SNES cart.
What kind of component is this, and how can I test if it works or not? Where can I find good replacements?
It's a piezoelectric buzzer. Probably like this:-
which has this data sheet. Small tip for the future. Google knows everything. Literally everything. I just typed the part number into it.
PS. I'm extremely impressed that such a crummy part has a frequency response analysis for it.

It's a 10,000 pF (0.01uF) axial-lead ceramic capacitor. It should measure open circuit on a resistance range of a multimeter and close to 10nF on a capacitance range.
Replacing it with a radial leaded 10nF 50V 10% X7R type should be fine.
