Updated crt-pi shader
-
I really like what scanlines do to the game art. But sometimes they feel a little too large and black. What is the best way to make more blurry and fade?

You can make the dark lines thinner by decreasing the value of scanline weight and make them brighter, and so less prominent, by increasing the value of scanline gap brightness. Both these values can be altered in retroarch using the shader parameters but you'll need to turn threaded rendering off whilst you make the changes. (There's a bug in retroarch that causes it to crash if you try to edit shader parameters with threaded rendering on with the gl renderer. You can turn it on again after you've made the changes.)

@dankcushions ok I think I understand now, when DaveJ wrote "playing vertical games on horizontal screens" it means vertical games that need to be rotated to fit horizontal screens. So if my vertical shooters are already in a normal horizontal orientation mode I can't add vertical scanlines to it by using the vertical shader, am I right?
I thought this vertical shader has been created to simulate vertical scanlines for vertical games on horizontal screens which seems not to be the case if I understand well now.i'm not sure i really understand. crt-vertical shader should be used for any vertical game regardless of how your monitor is orientated, as long as your settings are right. e.g.,
- with default options (with the vertical game in the centre of the screen with borders left and right)
- with a monitor physically rotated and
video_allow_rotate = "false"set in the cfg (vertical game is full length of the rotated screen, with no/less borders). with mame2003 you will need to use my new TATE mode option to get the right aspect ratio. other cores will need the aspect ratio set manually. see my recent posts.
-
@dankcushions by default options you mean that if I set the video aspect ratio to "config" (which is 5:4 on my /boot/config.txt) it doesn't work?

aspect ratio won't make a difference to shader rotation.

@dankcushions ok here is my SYSTEMNAME.cfg with no other specific game config for 1941 Counter attack for eg,,,all I get is a rainbow effect when I use the vertical shader:

that's not a standard retropie cfg file, for either /all/retroarch.cfg or (for example) /mame-libretro/retroarch.cfg. what do you mean 'SYSTEMNAME.cfg'? you can see what they should look like by looking at the backup rp-dist files in the same directories.
i can't necessarily see an issue it but it sounds like you're running an old version, or updated from an old one, or done something to it. you should also show a screenshot of your problem.

hello everybody, was busy these past weeks here is a little update on this one, when I launch the games from the 0.78 Mame set placed in the arcade dirtectory using mame2003 emulator all the vertical shooters shows vertical scanlines with no problems but when I apply the crt-pi shader on the same games using mame4all it always shows horizontal scanlines...I still don't understand everything yet on the subject I think!

I love the crt-pi shader, it seems perfectly optimised for the lowly Pi 3. I was just wondering if it's possible to adjust the intensity of the scanlines? They're just a little too prominent for my tastes and I'd like to dial them back a bit. I'm not sure how easy this would be as the shaders don't really appear to be adjustable but any advice would be appreciated!

In addition to the post dankcushions liked to, this post describes the effects of changing various scanline related parameters.

I run my 1080p screen at 720p for RetroPie, with the crt-pi shader. It's a modern screen and does a better job of scaling than the RPI imho.
@BuZz I was wondering if you could expand on this slightly. I've read across many threads that you run at 720p because of better shader performance on your screen.
At 1080p - I ran into the temperature warning symbol while running SNES (Mario All-Stars). I was trying integer scale and running the game at 1120 vertical because that game doesn't appear cutoff when slightly oversized. It looked flawless - but once I saw the temp. warning I took a step back. From reading other threads, I suspect my running the shader at that size (1120) helped cause the warning (combined with the fact that I don't have heatsinks on my RPi3)?
I just wondered what specific advantages you would cite for running at 720p? Do you use integer scale? (it helps that black bars appear smaller at 720p for the consoles, and the CRT-Pi shader looks fantastic at that res in IMO).

@RumblinBuffalo I am also interested in resolution and performance. I use a 1080p monitor for my arcade and I didn't set any resolutions, so I guess it's all at default, and using CRT-pi shader. I don't notice a performance hit, but perhaps 720p is better? Where am I going in my system to adjust this?
