Psp Emulator on Windows?

Okay. I have been on these forums for over 3 months. I just never made a account untill now, because im having a problem with the Psp emulator. I downloaded a game called "Final Fantasy Tactics The War Of The Lions" From a site im not going to mention. It is a CSO file, which im not sure what the file has to be to play on a emulator. I am looking for an emulator that will work for windows so i can play the game. I have a psp, and i dont know what the version is. When i was listening to music on it one time i was in my bannana chair and i was rocking i set it down on the ground and the chair smashed the screen. Now i cant play games on it. But i can listen to music on it and everything. It works perfectly fine, just the screen dont work. Can anyone help me. I wanna play the game but i dont know what to play it on.

They are no working PSP emulators yet. That file youve got is a compressed image of a PSP game which can only be played on a PSP using a custom firmware.
