How to play your favorite PS1 Games on PSP (FF7 Anyone)

First you have to have a 1.5 firmware on your PSP. If you are above 1.5, you have to downgrade to 1.5. The method right now is to get your hands on a Grand Theft Auto Liberty City Stories (Original Copy, they fixed it).

Next you download your appropriate downgrader and load that into your psp here:

You then load up GTA and load the saved game. That will start the downgrader.

Then you should be at 1.5 when you reboot. So now download this file here for 3.10 OE firmware:

Run the file under windows with the PSP plugged into your computer via usb. Tell it to install.

Then switch to the memory card section of your XMB (cross media browswer) of your psp interface and run the file that says something like '3.10 OE Installer'

It will not run unless your psp has been charged to over 75% power and is plugged in.

when it does run, after it is complete you should be on 3.10 OE and you should be able to play PSX games at this point on it yourself.

How to make your games into eboots that run on the PSP? For now read the readme that comes with 3.10OE, it explains how to use the Popstation file. I'll make a followup post on how to continue later on.
