PSP Emulator And Rom's?

I've been looking around myself but I can't find a working PSP emulator anywhere, and the games are just as rare to find and they never work. U might just have to buy it yourself sadly, but the PSP is still very much new and still in production so the chances of finding any roms for the thing are slim. And most of the time when i find an emulator, it turns out to be an emulator for another system ON the PSP, which only works on certain firmware versions anyway. Might be a long wait i'm afraid.
