You could try pSX (google it) but I've never had too much experience with emulators for PSX. A lot of emulators should be able to save to a certain memory card file thats pretty much universal, if I remember correctly from when I used to use Bleem. Then again, you might want to check the FF7 disc for scratches cause I know when I played through it the first time on the actual system, there was a scratch on the disc I rented that didn't load the exit point of the Gaia (I think that's what it's called?) mountains
so I couldn't move on to the next area. Didn't lock up, just wouldn't load the next part. I ended up buying the game the next day and it worked fine.
