'''tvout-tweaks''' is a shader<ref>https://github.com/libretro/common-shaders/blob/master/crt/shaders/tvout-tweaks.cg</ref> made by aliaspider, based off GTU, intended for processing emulator images for output to a CRT TV connected to PC via VGA-to-RGB adapter. This shader uses code from the GTU CRT shader to provide emulated signal bandwidth blur, as well as TV color level conversion. This shader is equivalent to the Blargg's NTSC filter RGB preset when the signal resolution is set to a high level and TV color levels are enabled. Works with any resolution without issues, lower signal resolutions result in a blur that blends higher input resolutions, allowing dithering to be blended and SNES hi-res translucency to work.
