Usually, the new PSP games come with an encryption; the idea behind the encryption (to be vague) is for security/protection purposes. JPCSP cannot emulate said games, therefore, you need to decrpyt these games with an actual PSP. I believe the process is changing the file's EBOOT.bin file and then re-packaging it, making it readable by the emulator (decrypted).
Now, as for Prometheus, it sounds like a tool to override the encryption? Or an alternative way of decryption? Regardless, I was reading what someone else said about it in another thread on this forum and I believe that it conflicts with JPCSP. Upon decrpytion, Prometheus probably adds an extra file to the .iso file thus making it un-readable by the emulator. Long story short, isos tinkered with Prometheus, most likely will not be able to run on JPCSP.
