Good evening everyone !

I've been looking for a while to activate a scanline shader with MAME... I'm a beginner & everything I find on the net doesn't work...

Can you help me please ?

Thanks best regards !

I don't think anyone here knows what a "scanline shader" is.

MAME already ships with shaders, and you just need to enable them, there's no need to install anything.

What platform are you running MAME on? That would be a good start.

For example, if you're on Windows, try running MAME with "-hlsl" on the command line. Bam, scanlines.

Hello thank you for your reply.

I am using MAME on Windows 7 & I would like to have a scanline curved rendering but I cannot find the options to activate this ?!

You're going to have to read the documentation and work it out. Repeatedly bumping your own thread makes you look selfish, impatient and demanding.

I waited several days without response I do not understand... I have already read the documentation there is nothing indicated...

You waited 18 hours on a major holiday when many of the devs have family obligations. And the documentation explains everything you're asking. Hint: look at the HLSL or BGFX sections. Both of them can do scanlines plus rounded corners.

Also, you gave no useful information. Did you try -hlsl as suggested by Just Desserts? Are you even on Windows? What version of MAME are you using?

Hello !

Yes I said that I was under Windows 7 with MAME version 0.216... I am a beginner I do not understand much sorry... I do not want the command lines thank you
