![]() ![]() I know there have to be overlays like the type I want, but finding them is near impossible as far as I can tell. It makes it harder to see the image, and I cant even figure out how to set it up correctly when its like that. Let me know what you think or if you need any help. I want an overlay for my Gameboy roms, but all I find are overlays that require the image to be shrunken down. 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 including support for custom palettes for games that were originally grayscale and displaying borders for games that include them. ‘ 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. This includes CPS1, CPS2, Neogeo, Genesis/Megadrive, Snes and many others. 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. Can be used to fill empty areas on widescreen monitors with artwork, display a CRT or handheld bezel, or simulate Game Boy Player and. 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. ![]()
