Daemon Tools works with PSX ISO's, as does a plugin whose name I can't remember that allows you to simply select an ISO file as your PSX cd drive, rather than a physical drive. You definately can play final fantasy tactics on epsx as mew barios mentioned. I've done it, and it worked really well with some tinkering.

You can find some ISO files on suprnova, but you can't download those, because that would be illegal.
