Reading of the configuration of the platform type (CPS1, CPS2 …) OR reading of the configuration set with the option “ –appendconfig PATH_AND_FILENAME.cfg“.C:\RetroArch\config\MAME\MAME.cfg (fot mame_libretro.dll).C:\retroarch\config\FB Alpha\FB Alpha.cfg (for fbalpha_libretro.dll).Reading the general configuration of the core for the loaded game, examples :.First reading the general configuration ( retroarch.cfg).This is the closest configuration to the game that has priority : When you start a game, Retroarch will test the presence of several files and load them if they exist. The directory of Retroarch contains a tree of this form, look well the directory C:\retroarch\config\ et C:\retroarch\overlays\, it is these 2 directories which are used to manage our overlays : C:\retroarch\ I’ll quickly describe how RetroArch handles overlays, Retroarch handles overlays, as much as using it. Moreover, if the emulator changes its display system or changes its system of options, RocketLauncher will not succeed, it also seems to me that RocketLauncher is dependent on “AutoIt” The simplest is to have a FrontEnd ( LaunchBox, HyperSpin, EmulationStation …) that directly launch your emulator (Retrorarch, Mame, Fba, Fba-Neo …) Why ? because the configuration is already not very simple, if in addition you add an extra layer, you will quickly get lost and especially spend a lot of time. My opinion, which can be questionable, is to avoid going through this kind of program. Here’s what it can do with and without overlays :Īlmost all emulators have a system of overlays, and when the emulator does not have it is possible to go through external program like RocketLauncher. The screens, at the time, were in a 4/3 format (rather square), now most screens are in 16/9 (rectangular), which leaves a blank space on the sides of the game. Overlays allow to add visual effects to an emulated game, it allows to simulate CRT screens or to add on the sides of the game an image that can be related to the console type, or in relation to the game itself. Let me know what you think or if you need any help.Today, I’m going to give you my feedback about the overlays in RetroArch. 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. 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. 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.
