Best PC PSX Emulator for screen ripping?

Hi experts,

What’s the best PC PSX emulator for ripping sprites? I’m hoping it will be one that A) plays using your computer’s CD or DVD-ROM drive to work, so that you can just put the PSX game in to play it and, B) one that captures clean screenshots, hopefully with a slo-motion/frame-by-frame keypress option.

Thanks!!
