Please show off what crt shaders can do!

Ha! Love it. There is something about putting over the top effects on these things that I quite like the idea of. Nothing to do with CRTs just putting a completely different art style in. I haven’t really experimented with the shader’s that already exist in this direction.


This shader is so fun to use, pretty much any game you throw on turns it into a whole new experience and I love it. Thanks for this one



That FX shader does really well with the arcade version of Strider!


For anyone interested I did a port of NTSC-Adaptive to ReShade :

Here we go another guest shader update another shader tweak. @guest.r I like the new additions especially that alternate bloom and luma grain, made good use of both of those. Just like my last post I included presets of both warm and cool temperatures to play with:

You must have guest’s latest shader update for my presets to display properly which you can find here.

@HyperspaceMadness you already know lol. As always, hope you all enjoy.


An example how i like to play some games, but is quite a quick setup.

Sometimes i find the Smart Edge Interpolation feature very handy also.


parameter values for the standard preset (copy/paste into an existing saved preset):

bloom = "-0.500000"
halation = "0.050000"
brightboost = "1.800000"
gsl = "1.000000"
scanline1 = "2.000000"
scanline2 = "16.000000"
beam_min = "2.499999"
beam_size = "0.750000"
scans = "1.750000"
scan_falloff = "0.500000"
h_sharp = "3.300002"
smart_ei = "0.200000"
sth = "0.100000"
warpX = "0.050000"
warpY = "0.070000"
csize = "0.080000"
bsize1 = "0.100000"
shadowMask = "6.000000"
maskstr = "1.000000"
mask_layout = "1.000000"
deconrby = "-1.500000"
post_br = "1.200000"

That looks great! Would you mind sharing the preset?


Sure, maybe it needs some more tweaking though. :smiley:


Good work from the master himself! Maybe you should start including your current personal shader preset as an example preset in your package from now on!

I could see this benefiting many users, both new and experienced alike.


Hello everybody! Well I made this preset with Hillian sinc, I confess that I would like to get this sharpness with the guest advanced mask 10, but it doesn’t get the sharpness like this:

It would require a special parameter with substractive sharpness. Been thinking about it since a long time ago and found a very nice code solution, will add it as a new release soon.


Great looking shader preset! I don’t see why you couldn’t get CRT-Guest-Advance to be as sharp though.

I used custom fast sharpen in this preset here, but in guest advanced I can’t add another sharpening pass after ntsc.

In this case, I used two sharpening shaders in this preset with Hyllian crt sync, the second being the adaptive sharpen.

I left the sharpen custom strength at max and the amount at 0, I left the rest for adaptive sharpen at 0.80. With luck I think I got a not too destructive result.


Interesting, I use CRT-Guest-Advance via HSM Mega Bezel Reflection Shader so there are a couple additional options available to me. I haven’t really mastered using the CRT-Guest-Advance-NTSC version and I’ve been instead using Blargg NTSC video filters with custom settings where possible in order to incorporate NTSC artifacts into my CRT Shader presets.

Within HSM Mega Bezel Reflection Shader I get to use Horizontal Sharpness, Subtractive Sharpness as well as Fast Sharpen. I think the Blargg video filter also has a Sharpness setting but I haven’t found the need to adjust that as well.

This is the result:

If you’re still getting proper transparencies in the Sonic The Hedgehog Waterfalls with that level of sharpness on the edges, I think you’ve done a fantastic job there!


Hey thank you so much!! This is amazing!! It’s better than I could have imagined!!

before and after (my preset on the left, your update on the right)


I’ve noticed in your screenshot that although overall sharpness is improved, you can now notice the individual vertical lines (jail bars) that make up the waterfall which were more blended in your older screenshot producing a more convincing transparency effect.

Here are some examples using the “old” CRT-Guest-Advance in HSM Mega Reflection Shader using Horizontal Sharpness, Subtractive Sharpness and Fast Sharpen plus custom Blargg SNES Video filter settings to do transparency effects.

You have to load full resolution then zoom in or view fullscreen in order for these to look correct because of the mask and scanline settings.

I found that what caused this in the jailbar was Ringing, I set it to 1.100000. Actually this way is good for me, because Master System games are more blurred, since I only use one preset for several colors. The ringing made things much better.

But I tweaked it a little more, and lowered the ringing to just 0.200000, and the rest of the sharpening settings looked like this:

Ringing makes a lot of difference! even at 0.200000 it already provides a good highlight!

SHARPEN = “4.000000”
CONTR = “0.140000”
blendMode = “2.000000”
h_sharp = “0.900001”
s_sharp = “1.500000”
ring = “0.200000”
