I'm using 3.10 OE A, although I haven't tried any of the FF games yet, it's worked perfectly with the games that I have tried (except for Castlevania SOTN wich has some miner graphics errors) The only time I had the black screen problem you describe, it was because the iso I was using was bad. Making new clean rip from my cd fixed the problem. Not with the ripper included with popstation though - that thing crashed my pc when I tried to use it. Instead I used nero and a prog called nrg2iso to convert it into a standard iso format.

Also, from what I've read, 3.10 is actually supposed to to fix the pal emulation so you shouldn't need to us PALadin with it.
