![]() Let me know what you think or if you need any help. Scanline with aperture grille 50% opacity Scanline with aperture grille 75% opacity Scanline with aperture grille 100% opacity You can do this in firefox by right clicking the image and selecting ‘VIEW IMAGE’Ĭloseup image showing the 2 overlays in use at 2x the size and at various opacity levels: Be sure to view these at full resolution otherwise they won’t look correct. ‘OVERLAY OPACITY’ and adjust the opacity by pushing left or right.īelow are some example screen captures. You can change the opacity of the overlay to your own preference by going to: ‘ scanline-grille-1080p-224.cfg‘ is scanlines with an aperture grille effect as well ‘ scanline-1080p-224.cfg‘ is just scanlines ![]() Once in Retroarch go to the menu and under settings goto:Īnd from here select one of the overlay configs that you copied over. Then: ‘USE VIDEO OUTPUT RESOLUTION’ (assuming that you have your rpi set to 1080p). You can set this by pressing ‘x’ after selecting a game. To use the overlays unzip the archive which I will link to below and copy the directory to the following location: /opt/retropie/emulators/retroarch/overlays/effects/scanlinesĮnsure that retroarch is rendering the display at 1080p. The 'ambient glow' border shader samples the average color over time, and it would be possible to use that data to modify the color in an image, as well, though nothing like that exists at the moment. This includes CPS1, CPS2, Neogeo, Genesis/Megadrive, Snes and many others. The overlay system doesn't support any means of pulling color information from the content, so it's not possible there. To start with I’ve created two overlays suitable for use with systems that have a vertical resolution of 224. ![]() ![]() The downside of this approach is you can’t have a “one-size fits all overlay” as there are several different resolutions that systems use and so you need a different overlay depending on the vertical resolution of the game being played. My overlays are pre-scaled so that they match perfectly with the scaled game image. Most other scanline overlays are designed to be used with integer scaling switched on but the downside of this is you either have a black border or lose some of the image. Most of these overlays need a curved CRT shader to avoid cropping too much in the image corners.I wanted to use scanlines but also wanted to display games using the full height of my TV so have created some retroarch overlays to achieve this. You will then be able to access them from the Quick Menu. ![]() opt/retropie/configs/all/retroarch/overlay To use these overlays, you will need to place the CRT folder in your overlay folder on your Pi: I'm still working to perfect these, and once I get a good groove going, it will be trivial to expand the library of overlays. (Scanlines can show weird moire patterns when downscaled, so please click the images for full size.) They're designed for 960x720 4:3 1080p and the CRT-Pi Curved shader.Īll of the pictures below were taken directly on my Pi 3 B+ using raspi2png and look exactly as it does on the Pi. Each of the current overlays has an optional screen-glare variation. I'm working to create a moderately large pack of CRT overlays, but I'd like some help from the community with supplying some good images to work from. This is my first post here and I wanted to show some stuff I've been working on and would love some feedback.
