I'm not sure if this the correct place to post this. But, I've been going circle with trying to install RetroArch and Kodi on my pi3. But, yesterday, I've just discovered that if I turned on the KM OpenGL then the RetroArch won't lag and I can play retro games on it. But, the core seems unable to download. And, another thing is if I off the OpenGL using the raspi-config I can then able to open Kodi. All along I thought, there's something wrong with both installations or version. Also, while playing Kodi, it will suddenly blackout. I know this questions been asked for so long but, anyone else already know how to solve these problem using this both apps? I've tried installed Retropie, the gaming part does work but can't make the Pixel desktop and Kodi to work on it.
