In current SVN and the upcoming 0.154, all drivers should use rgb32_dir.fsh. That's part of my simplification of the OpenGL renderer.
There will also be a GL 3.2 profile renderer path probably later this year/early next, around the same time we switch over to SDL 2 by default. That of course allows longer/more complex shaders.

Well I don't really need anything else. I had re-added the aperture mask effect before but had it hardcoded to my preferred resolution. It was easy to make it work properly once you added the "screen_texture_sz" uniform. The few other things I changed were color adjustments and such that don't need anything more from the GLSL system. I guess that some people may want more complicated stuff (access to previous frames for blending, extra textures to render to for bloom effects (isn't that how they do it?)) but I'm pretty happy the way it is. If the shader could be longer, then I could add different horizontal scaling types, but this is really not necessary because I could just switch it to cubic (instead of lanczos) scaling and use different values of "B" and "C" to adjust blur/sharpness/ringing to preference.

Good news to me.

Yes, it would be fantastic to be able to render to an intermediate texture.

You already can in terms of how the shaders get chained: when I run NTSC into CRT-geom NTSC first renders to an intermediate texture and then CRT-geom works from the intermediate texture. But I know that's probably not quite what you had in mind

Slight follow-up on this, can you supply different settings for multiple game screens? A la Punchout, to get the bottom screen tilted back a bit..?

I wish. Both share. 
By the way. After 0.154 release then I will do more.

I'm feeling a little silly as this doesn't seem to be working for me.
In the MAME.ini file, in addition to all the other settings, I have:
Code:
glsl_shader_mame0 shader\tv
If I wanted to apply the setting you posted above only for a specific game, what should there be in the game specific ini file? For example I wanted to setup the tilt on donkey kong, so I created a DKONG.INI. It keeps trying to open a shader file with that name: overscan(1.0,1.0)_radius(2.0)_tilt(0.0,0.0)_corners(0.03).vsh
I know I'm going to face-palm when it is explained to me.
Thanks!

glsl_shader_mame0 shader\ "What ever you want to use here" and then save it.
If you wanted to just use the MAME folder instead of the shader or shaders then do this. A lot easier.
glsl_shader_mame0 "What ever you want to use here" and then save it.

Humm, I tried that and it is still trying to open a shader file.
Let's say, as an example, I want to set up a dkong.ini so I an change the overscan value.. let's say overscan(1.0,1.0). If I put:
glsl_shader_mame0 overscan(1.0,1.0)
In the dkong.ini file, SDLMame tried to load that as a shader file: overscan(1.0,1.0).vsh

I'm not sure how this would work from a UI perspective, but what I had in mind was the ability for a shader to render to an intermediate texture of arbitrary size, and then the next shaders down the line can access both the intermediate and the source texture. Maybe there can be a special formatted comment, like
//$output(int0, 0.1, 0.1)
and then the next shaders could access both the source texture and int0, which would be 1/10th the width and height of the source?

You just renaming the file. Doesn't change the settings at all. Only way to change the settings is to open the file with Wordpad and then edit it.
Another thing is that if you just rename that "Bah Bah".vsh then you gotta rename the "Bah Bah"_rgb32_dir.fsh file as well. Rename what is in the " ". Both files connected together by linking.

Ahh, you made it seem like you could pass parameters to the shader via the INI file. If it is just creating a new shader file set per setting, then I got that covered.

I been editing the files to make new ones with new settings. That is why I have over ten of those each.
