That looks pretty comparable to the “RGB Shadowmask” configuration which is pretty awesome, MAME is brighter on this default compared to this Analog TV pack version.

But what I was looking for was how this pack + retro arch can emulate the TV look/feel. In the config menu it has listed 12 shader passes from the config to make it look like an old POS TV. I’d have to ask how to make MAME look like a blury smudgy washed out mess, as I’ve only recently found this stuff. If this helps at all to show the difference.

-video bgfx -bgfx_screen_chains hlsl

This will give you a “stack” of the following shaders in the following order:

– NTSC encode/decode (to apply color fringing for e.g. NES games)
– Color convolution (multiply each RGB triplet by a 3×3 matrix, as well as applying separate offset, scale, and saturation values)
– Convergence (both radial and linear)
– Focus
– Phosphor decay
– Geometric distortion applied by the monitor (pincushion, vignetting, internal reflection, corner rounding)

If this is not the sort of “stacking” that you’re referring to, please give a more clear explanation, as I’d be happy to bring MAME up to feature parity with RetroArch’s shader system.

Where though? I only found HLSL, but I don’t see anything about shaders or stacking them.
