i have try the emulator from the lest 2 days and it's marvelous. But since the afternoon, i have a little problem of speed. When i played a game before, it was at full speed (60 fps) and my CPU was used at ~50%. But now, i have a speed of 53 fps and a CPu use at ~10%. And i have whange nothing in my config or the emulator config.
Maybe you should close some outside programs before you go about using this emulator. My load up screen loses 10 frames when something like BitComet is running, but full-screen keeps it's 60 FPS no matter what.
