effect parameters in "# CORE SCREEN OPTIONS only for 1 monitor possible?

[xbrunox]

Hi all I've a cab with multimonitor systems.
a CRt and an LCD.
i want to apply effects only on LCD monitor and not on crt monitor.
i know that i can do it using BGFX and bgfx_screen_chains.

little problem... on my cab I use a groovymame version. and groovymame don't work very well with bgfx and different screen chains.

instead if i change effect line in core screen options and use a simple scanlines.png i can use d3d and for me is good.

but i want that the changes are applied only on my lcd (for mame \\.\DISPLAY1)

there's something that i can do with cfg files?

any suggestion?
thanks.
