What disk do I need to boot with or action replay do I need to get FF chronicles and Hoshigami to wo

It doesn't matter what disk you boot with as long as it's and original Playstation disk. There's a sector on all PS disk that the Action Replay needs to read and then you can go on from there.

As for the blank screen it sounds like a speed copy issue, speed kills PS games, if there ones I reall care about, 1x or 2x but I don't have burn proof software.
