There’s this old thread on neogaf regarding scanlines, where people post captures of their setups. Some are real crts and upscalers, others emulators. Some look great, others quite bad and unrealistic. I keep reading about how good this and that shader look, but I don’t see many images, and those tend to be worth a thousand words indeed.
Retroarch shaders are the best in the business, but not always easy to implement, and we can learn quite a lot from each other. So let’s go, I will start with many examples of settings that I like, from different systems : )
