hey numbnut, you could download the latest 6.20 cfw here:
Downloads - procfw - X-Generation Aftermarket Firmware for Playstation Portable

the 6.20pro-b8 is pretty stable, but the b9s are just beta versions, so we're not pretty sure if it's gonna run your psp to what you wanted it to be like. or

you could just update to 6.39, and run all latest game and upcomming games.
sony ofw 6.39: MEGAUPLOAD - The leading online storage and file delivery service
cfw 6.39me9.1: neur0n - PSP Developer

run the 6.39 ofw updater, then run the cfw updater. go to system update and update, congrats, you're now on 6.39me9.2.
