PSP Downgrade

Hello, I just bought a PSP & the system software is version 3.80. Is there a way that I can Download games onto my PSP's memory stick to play them?

you can only download and play games on your psp that i know of by installing custom firmware on your psp.
and just incase your next question is ''can i get custom frimware(CFW) on my psp even tho its really high up in the orig.firmware?'' the answer is yes.
i did my psp from OFW 3.90

What firmware version should I get and how do I use it?

If you search the forums, there are lots of guides and tutorials that will show you what you need to do, I think you need a Pandoras Battery to go from 3.80 firmware though.

If you only have your psp to work with, then follow my guide on how to install CFW with only 1 psp in the tutorials section. It's the ONLY way to do what you want to do.
