The short answer is NO and NO. But you will have other emulators.
The long answer is: There isn't any PSP emulator that works 100% good in PC (well Sony have one, but is private). Remember with no source code, we can't port. The NDS emu is more probable, the cpu are ARM in both, and there are source code of some emulators for PC. But there isn't any coder working in this (I think), because the screen. Moreover, if you like NDS games you're going to buy a NDS.
P.D. This thread must be in Pandora forum.
