Best PSP Emu, downloaded JPCSP but don't know how to play games .cso file?

i just downloaded a torrent of crisis core .cso file, and can't seem to play it on JPCSP. Granted, I've never tried a PSP emulator in my life so i'm not too familiar with anything.

Any help would be greatly appreciated. Thanks

have you tried the non java version?

If the emulator does not work with .cso files there is a program that converts .cso to .iso.

did you run it in umdimage
