Hello, howdy, and how do I pull of 50Hz@emu & 60Hz@host ?

[Einstein]

Goal:
To have WinUAE to "blit" the display buffer (current buffer) of the emulated Amiga every 1/60 of a second (60Hz) while the emulated Amiga keeps its own pace (PAL) of swapping the buffers every 1/50 of a second (50Hz).

Obviously I want to pull it off to have smooth scrolling in PAL mode (regardless of the little display artefact we are familiar with). I can raise the FPS to 60Hz offcourse but then the emulated Amiga follows up to 60Hz as well, which obviously isnt 50Hz anymore  :crazy:  and causes an annoying laggy scroll experience, so how do I do it ?

Thanks !

I will investigate that Powerstrip, and meanwhile a little correction; I wrote that changing the FPS from 50Hz to 60Hz causes annoying lags, not true, in fact it creates smooth scrolling, but in 60Hz. This FPS raise however also causes the emulated Amiga (I wrote correctly this time) to raise its display buffer swapping from 50Hz to 60Hz, which although smooth scrolls, it does it too fast obviously.  :pissed:

Since my Plug-n-Play (^_^) monitor doesnt _seem_ to support refresh rates below 60Hz and above 85Hz and I dont have the guts to force the desired rates with Powerstrip I'm not going to get my 50Hz (or 100Hz) smooth scrolling experience am I ?
Dammit this is annoying, all (Win)UAE needs to do is to flush the emulated amiga's current display buffer at 60Hz while having the emulated vertical frequency set at 50Hz, and I would be a happy Virtual PAL Smooth Scroller fellow!

In order to do this, to my knowledge the emulator should have to create frames which are not in the original animation.  Every new frame should be an intermediate drawing between the previous frame and the next frame.  In order these frames to go unnoticed, the emulator should use a combination of anti-aliasing and pixel scaling methods, which would depend on the emulator's screen mode and the computer's power.  It might be a complex thing to program - but I'm not a coder - and would require even more processing power.

Well, forget about it needing to be unnoticed, I take anything smooth scrolling at 50Hz that I may experience.
I probably should have simply written that what WinUAE needs to do (as an option) is to forget about vertical syncing the host computer display to that of the emulated Amiga display, that is, it _really_ (I'm desperate) should (as an option), simply as I wrote, to flush the emulated amiga display (that the copper bitplane pointers point to) once every 60th of a second, this while updating the copper register(s) that hold(s) the current vertical beam postion (yea I dont remember the names and such) at a rate that it vertically resets once every 50th of a second.

MAME does this beautifully, I dont see why (Win)UAE wouldnt be able to perform this simple task !

*edit*

Offcourse MAME knows no copper!  ;-)
