PSP Downgrade, custom firmware, and emulator?

[odnam92]

Ok, so I recently figured out that I could run Snes and Nes emulators on my psp, but that I have to run on custom firmware. So basically I need help finding these things (If they exist)
I need a downgrade from version 3.80
I need a custom firmware that will allow me to do all of the things, or most of the things that my current version will let me do and not brick my psp.
I need a Snes and Nes, and maybe a N64 emulator.
Any help finding these would be appreciated:)

There are no downgraders for 3.80 or above, you're stuck with using the Pandora Method*. Dark Alex's M33 series (http://www.dark-alex.org/) is the recommended custom firmware. Until you're there, it's pointless recommending emulators.

*Using a Pandora Battery and a Magic Memory stick to downgrade down to firmware 1.5, where you'll then, and only then, be able to install your custom firmware.

Ok I have no idea what you mean by the pandora thing. I clicked on the link and don't know what to do from there. So, what do I do from there?

Search this Help forum with the keyword "Pandora". Basically, you're modding a normal PSP battery, and a normal Memory Stick (512MB/1GB preferably) by using certain files so it can be used as a downgrader. I'd be better help but it's 2:30AM here and I'm nackered.
