PSX emulation on PSP

[Lordraviel]

I have recently got a PSP, unfortunately with firmware 3.90 but I have ordered what I need to solve that along with a 4GB Memory Stick.

I am interested to know how good PSX emulation is I have seen Videos of FF 7, 8, and 9 running which is good enough for me, but my question is what is done about games that require analogue control, and what about L2/R2?

Tomorrow I get my Pandora's battery and I can start sorting everything out.

Basically I want a quick overview of what files I should be getting, what I should be doing, and In what order. I can search for details myself but a rough Idea wold be helpful.

I have...

EU PSP Slim with official Firmware 3.90.
a 1GB Mem Stick.
a 4GB Mem Stick.
and the Pandora's Battery when it arrives.

I am looking to emulate NES, SNES, and PSX and possibly PSP games as well (to avoid carrying them around with me of course).

Any help would be appreciated, Thanks
