Video Effects

Eagle

: doubles the rendered picture size with some dithering effect to avoid square pixels. This effect only works in 8bpp, and does not work often in the accelerated win32 driver.

Scale2x

: Same goal as eagle but without the «blur» effect of the dithering. This effect comes from the AdvanceMame project at this place.

Pixel double

: Same as eagle but without the dithering effect. You will get square pixels but it will work in any color depth.

Double width

: can be useful with scanlines.

Stretch Max

: Stretch the rendered bitmap so that it will take the largest area on screen while still keeping its aspect ratio. Warning : this option as well as ``Stretch FS'' is using software blits until now so they take some considerable cpu power !

Stretch FS

: FS is for Fullscreen. Stretch the rendered bitmap to display it in the whole screen (no black border). Of course, you might loose aspect ratio here, and in this case your picture will look weird.
