Well if you want an emu that plays FF9 I'd recommend ePSXe, you can download the ePSXe installer @
PSXEmu , and for the BIOS which is needed to run the emu just type scph7502 in the search bar of your favorite search engine and you'll find lots of sites.
And don't ask for it here or you'll be immediately banned as it's illegal to distribute BIOS rom images...
For how to configure ePSXe check the
ePSXe FAQ
