Custom PPSSPP shaders

[dcloud466]

This seems nice. I see the emulator already has two sort-a scanlines filters included but I wonder if and how I can add in my custom filter. I already read up on adding the filter in the list, and making a "vsh" or "fsh" filter text file. Adding the lines in the "defaultshaders.ini" file.

So how can I get just a simple 100% black scanlines filtrer added to that list that'll work?
Or a simple 100% Black Grid filter added in?
- Also - is it just me or do those post processing shaders only work with opengl? Of course I never got any of them to work using directX so it must be.

Technique really only applies to 2D imagry.

I don't really like the Tv-CRT filter as it adds extra colors and doesn't really "filter" anything. I know it's trying to mimic the old TV set but even back in the day my TV had a better picture than what that filter. A Normal Scanline filter Removes the extra horizontal pixels created when it's been resized giving it a legal Filter alias cause that's what it did. Adding a Grid scanline is the oposite, it can take care of all the extra pixels created after resizing. Of course it should cater how many times it's resized wether you need just a 1 scanline application or 2x scanline application.

It seems to be just a matter of adding the filter code to the text file but how..?

Thanks!

Here's how the normal simple black scanlines filter would look
