Figure i'd start a new thread. Forgive me this will be light on screenshots as i'm dead tired but here is a comparison shot of the various options to choose from. If you guys would like to test and contribute that would be nice. No need to muck with anything, just select the corresponding .cgp file in the folder of the pack and get to enjoying some CRT-esque goodness.
Bear in mind you'll need the latest retroarch that supports a higher number of shader stacks, although I managed to keep the resource level down, I have a 4 year-old Dell XPS and everything runs smooth on my end, obviously YMMV. It should be a nice alternative to CRT-royale which my machine has trouble keeping up with when combined with other shaders
The versions you can choose from are:
480p: Nice shader suitable for 480p content like Dreamcast games
Component: High-quality signal look but not overly sharp like RGB
B&W TV: Pretty self explanatory
Vintage TV: This looks really good with low-res pixel games on systems like the Atari 2600
Vintage LCD: Looks like an early gen LCD screen complete with ghosting
Composite: Simulating a typical cheap CRT using composite cables
S-video: Much the same but better quality video signal
RGB-Shadowmask: This is more akin to a high quality CRT with RGB/SCART cables
RGB-Scanlines: Like the previous but with thick bold scanlines like you'd find on a Sony PVM or other broadcast quality monitor, nice and bright
As a sidenote i'm not including any overlays, there were some issues last time with people with different sized screens and resolution and now that retroarch supports overlays in the menu that you can adjust manually, people can select their own from the various ones out there. If there is a demand though i'll include the old one I was using.
Here is the link to the files
Thanks to everyone whose shaders made this possible, particularly hunterk he's been real helpful.
