Need help with FFVII savegame loading

Hey all-

I downloaded FFVII off of PSPISOz and got to Disc 2. When I try to load Disc 2, it won't locate my save file. It's there on Disc 1, but my PSP won't acknowledge it on Disc 2. :(

How do I load my save file on a different disc? I am very, very new to emulation - I had a friend hack it for me and he doesn't remember how to answer my question - so please explain it to me like I'm really stupid. :)

I'm running 3.90 M-33 firmware on the oldest possible model PSP. Please excuse my extreme newbishness.

Not to be a downer, but I'm pretty sure you can't talk about those ISOs you, ahem, acquired.

With that said, load up disc 2 and then press home and go to memory card utility. Then you need to select the option up at the top that changes the title of the game up at the top of the screen until you see your little save icon pop up on the bottom half, should be a picture of Cloud's head I believe. Then import it over to the left side of the screen and try to reload it back in the FFVII menu.
