I've been playing FF7 for a while now, and even though it's a little fast I think it's enjoyable. You don't have to have your games in .psx4all, but you need to put the bios files in the same folder that your games are in. I had my games on the SD to begin with too, so it's not a problem. Also, changing the bios in the psx4all options may make it work better-I hope I'm helping
