Home Page Forums MAME MAME How to install a scanline shader with MAME ?

Then what do you want? No one understands what you want.

I don't understand how to have the scanline curved filter...

You can try the following:

or set the two options in mame.ini if you don't want to type them in every time.

Make a mame.ini by using this command. mame64 -cc

Then paste these in there over the old settings.

# OSD VIDEO OPTIONS

# DIRECT3D POST-PROCESSING OPTIONS

hlsl_enable 1

If you want rounded corners. I using these below.

distort_corner 0.02
round_corner 0.10
smooth_border 0.01

Just 0.0 those out. If you don't any of this showing. Should look like this.

distort_corner 0.0
round_corner 0.0
smooth_border 0.0

You will get a hang of the settings. Take a while.

Hello !

OK thank you for your help I will try... & how we modify the parameters of the scanline, to have a more or less important space between the scan lines ?

Thanks best regards !

Hello

In my HLSL folder I have this:



I tried the following command:



But I have this error message:



I tried with another filter & I still get this error message ?!



No filter works !!!

There is no argument to -hlsl. So:

OK but then how to choose the filter in this folder ?

You go to the sliders (~ key, or Tab and then Slider Controls) to control all the parameters. All of those files are auto-used.

I am in " Slider controls " but I have no options for the filters ???
