By the way did you know about the problem with the sound stuttering Epsxe core on Final Fantasy V?
I think you don't understand or maybe me but about the f7 trick: I use f7 when graphics are missing (it will change to peops soft gpu when I press f7) the problem will be fixed for the moment but when I go to other places again I will have to use it because the graphics will be missing (maybe I'm wrong but that is my problem).
Anyway as always thanks for your response and help
