Scrolling so jerking on non-NTSC systems

Scrolling so jerking on PAL and Dendy/Hybrid systems even if "Sleep Between Frames" is ON.
Other emulators does it more smoother (even at 60Hz physical display refresh rate).

While it does look better with the display set to 50 hz, you're still right.
I think it has something to do with the length of the audio buffer as that's still set in 60ths of a second

Well I fixed that much, and now 50 fps games look as good on a 50 hz display as 60 fps ones do on a 60 hz display. That's some progress though I can't do much more without a proper vsync. Maybe there are some other undiscovered problems with deriving so much of my timing from the audio buffer in the way I do.
