Need an opinion

My sister has got a PSP3000 on OFW 6.35. She'd like to run some basic emulators, like snes and whatnot. What would be the safest way to go about this? Can you still self-sign things at this firmware safely?

--edit--

Sorry, I realize that I can google this but I'd rather get the opinion from people I trust.

Well, the best route would be used a signed emulator!

In such case, using a trusted emulator is the way to go!:)

To run emulators on a PSP3000 with OFW 6.35, you'll need to install custom firmware (CFW), which involves certain fnf risks and may void the warranty.
