3.52 M33 help with emulators

I just got my psp running 3.52 M33 firmware. thanks to a friend thats much more knowledgable in anything software/hardware related then me. But the question is, how do I load an nes/gba/pso emulator and games onto it? I've checked the forums and a good number of the help forums, but cant seem to find the answer and I would usually just trial and eror with things like this (or take a hammer to it untill ot compies) but I am afraid to brick the psp.
any advice you have would be appreciated and thanks for your time. (I'm not stupid, I play bass)

i highly doubt you could brick a psp by trying to run emulators on it...

Just find an emulator you would like to try.... then look at the readme.

If this is not allowed, I am sorry, but once I've found N64/Gameboy/etc. emulators, where do I find the games?
