How to run a ISO game on a PSP emulator?

[gulips]

Hi guys, I've got some problems about running "Birth by sleep" on psp emulator.
It's my first time with these stuff and I got stuck just after unzipping the game.

I'll describe now what I did step by step, so in case you can find my mistake:
1) Downloaded the emulator. It works.
2) Downloaded the file of the game. It was in RAR so I run the Rar program to expand it.
3) I was lost here, because there were so many files in a format I couldn't open, BUT I found another RAR, so I guessed that was to be expanded.
4) I expanded this file and found inside a ISO file and I tought "That's it, now I can run the game!"
5) Of course it was not. Life can't be so easy and happy. I got stuck here.

Other informations:
I'm a Mac user and the emulator for psp I took is jpcsp. I really AM stuck.

Please save me.
And I'm sorry for this silly request.

The ISO needs to be in the "umdimages" folder of the emulator.

I tried, but the emulator scolds me about piracy and then refuse to run the game

Ah, so you're getting an error message of sorts? Copy that message here please. (the problem might be the ISO, but I want to make sure)\

Edit: My guess is that it's an ISO patched to be used on an actual PSP via custom firmware. You might want to Google "how to remove prometheus patch from iso" and see what you can find. I think you can do it with UMDGen but I'm not 100% sure.

I think you are using a build that still requires the game be decrypted, so try one of the latest SVN builds.

I have a question on this as well. I downloaded a psp file from here to play on my psp (with custom firmware) and i had the same problem as him unpacked to find other rar files and extracted from there) and the game still wouldn't load. i even copied the folder into my ISO folder and still nothing
