No, they are still early in development. They will not run on Crisis Core at all. Wait at least 5 years.
The PSPE emulator is for homebrew only and it is useless for psp isos.
Keep your eyes on Potemkin and PSPPLAYER emulators. They are very promising. PSPPlayer can run Buzzle Bobble (JAPAN) fine with a few glitches. Be patient.
