Topic: Overscan...

[wcoder]

Hi,

Is there's a way to draw overscan part of the screen (Like WinUAE) ?
- Soft evolution or config file ?

Not without editing the drivers, and changing the screen to the visible size + overscan and removing any of the visible offsets from the drawing functions.

Thanks for your answer...

With 1943 - CPS1, I try to change 224, 384 to 228, 391 (try to keep ratio)...
The result is a black border one right and down...

In your answer you speak about an offset: where this code is located in this case (or any other with a rom available at gametronik ... useful for live debug)...

Thanks for your help...

   NULL, NULL, NULL, NULL,

};

No need to worry about ratio, if you select "Correct Aspect Ratio" from the menu, the aspect will always be scaled.

Any drawing offsets are driver specific and vary greatly in use. For example, in cps_draw.cpp you will see this several times,

Code: [Select]

nScrY += 0x10;
This offsets the drawing by 16 pixels to account for the non-visible area.

Thanks for answer,

I found the right file... but my change don't work ...  (^_^)

With the right variable : INT32 nOff, nScrX, nScrY;  it will we more easy ...

Thanks,
