crt-pi shader users - reduce scaling artifacts with these configs in lr-mame2003, lr-fbalpha, lr-nestopia (and more to come)

@caver01 Yeah. I was using them on my 1080p monitor. But on CRT without shader, I can just barely see the monitors own scanlines. The effect is very low and with added shader, it looks better to me, at least on systems like snes.
-
@thelostsoul That's really interesting. I need to do a CRT build at some point.
-
@thelostsoul at 640x480, you won’t see a CRTs natural scanlines. they’re not part of the monitor, but the way a CRT displays a 240p image.
you need to set your pi up to send 240p to your CRT if you want to see what they look like.

@dankcushions I tried it and it looks awful here. Not sure if i messed it up somehow when trying out. Or maybe it does not work good with this monitor. In any case, I really like the output of this shader.
On my snes I like the output, but the arcade games need different settings. Thats why I don't just want use single setting for all games.
I tried to show the differences with smartphone screenshots from the snes emulator. Also this shows why we really need scanlines. It makes the image more natural and gives depth and shadow to it, hiding the edges. LEFT is without shader on CRT monitor and right is with shader. Look how organic the head becomes.
If there is an interest, I can give a much bigger version of this comparison image.

@thelostsoul looks like that's a crt pc monitor? that's a slightly different proposition. they have a way higher resolution than a normal TV so i would guess the scanlines don't manifest in the same way at 240p.
according to the specs it runs at 1600 x 1200 so you could use this shader effectively at that resolution, and even build some configs that match that resolution, using this script (although they probably won't help much at 4:3)
-
I just wanted to say thank you for making these!
-
@dankcushions This is great! I cloned your script, but is there a way to have it also create a perfect height integer for all non vertical games (Mortal Kombat etc)? So basically do the opposite of what it does now, and just set the perfect integer on horizontal games to keep the scan-lines even for horizontal games?
I have tried various tolerance settings, but I can only seem to get 1080 in my tests.
-
@dankcushions will this shader pack work with your MAME/FBA scanlines config pack instead of the simple CRT_PI?
Thank you

trying to cast my mind back - no i'm not sure you can. but it sounds to me like you just want to set integer scaling on, and don't need the script? what kind of display are you using?

hi! what shader pack? i'm not sure i understand :)
-
-
@pyjamarama ok so:
with your MAME/FBA scanlines config pack
what's my MAME/FBA scanlines config pack?

@dankcushions I am on a 1080p display. I have all of my emulators integer scaled for that resolution. All of my systems except for neogeo have very minimal/zero offscreen crop. I absolutely LOVE what you have done here for vertical games and it works so well.
I was wondering if there was a way/flag (and this might be a feature request) to have your script do a "horizontal" mode based on the tolerance setting, to set the height to an integer as well just for horizontal games.
So for example at 1080p the integer height of Mortal Kombat overflows the screen to much at 1270 (5x). But at 1016 (4x) there is a very small amount of black bars at the top/bottom which I don't mind. As your script seems to set every cfg's height setting to a static 1080 based on my 1920x1080, it would be cool to have it set the height to either a 5x or 4x integer depending on the tolerance setting.

@dankcushions is there a corresponding folder to place these config files for mame2003-plus?
My full size arcade cabinet Robotron vs. Octolyzer
-
@robertvb83 it should be /mame2003-plus/
-
@dankcushions i tried that but it is not loading the config on gamestart

sorry, this:
MAME 2003-plus -
thank you, thats working

@dankcushions Is it possible to convert this somehow for 640*480 CRT VGA monitor (480p)?
I use a pc monitor with that resolution, but the monitors scanlines does not make a big difference at that resolution. It does not support 240p, the point where I wouldn't need any shader. Thats why I use some sort of shaders here and I really like yours. But it looks often very bad for this resolution.Edit: Sorry, I saw the link with the script for creating the package myself. I will download and try it myself first.
Edit2: OH, but I think this will not help me with the other consoles right? I would need a shader specifically for 480p.
