When trying to play with emulators that focus on accuracy rather than emulators that focus on upscaling, a shader is very important for the experience. Getting the right shader can rival even emulators with upscaling.
I've spent the passed few months, trying an assortment of libretro shaders, and have had success with many of them. From CRT shaders that would present all the pixels in their true glory while being smoothed over with minimal scanlines, to shaders with algorithms that would smooth out the pixels enough to make retro games appear HD.
However, I was never truly satisfied, because either the scanlines were distracting while not providing any enhancements, or the other shaders that would HDify everything still suffered from a lot of quality loss or distortion.
Well, a few days ago, I ran across this thread:
http://libretro.com/forums/showthread.php?t=2397. The first shader in that thread, seemed to be almost exactly what I was looking for. It was literally the best of both worlds.
There were just two things that needed tweaking: the shader wasn't very bright, and I wasn't a fan of the warping.

So I present to you, my tweaked version of the aforementioned Shader Preset. I've tested it out on SNES and Playstation 1 games so far, and it's absolutely amazing.

Save it as "xBRMultiLevel4+CRTLottesHalation-tweaked.dll.cgp" for example, and tweak the paths to match your RetroArch version.
Here are a few screenshots (the screenshots add vertical lines for some reason, which do not exist when using the shader):

If you want me to take screenshots of other games, I'm more than happy to, or if you need helping setting this up in RetroArch, feel free to ask for help. I hope you enjoy this as much as I do.
