I have a weird problem. I recently installed RetroArch following ETA PRIME tutorial on youtube I installed the final burn alpha 2012 libretro core but when I load any neogoe game it crash. I then installed the fbneo libretro core. This core load any game without crashing. Sound work but I get no image/display. I can hear the game working on the background but I cannot get video. if I switch core after using fbneo core let say I go back to fb2012 libretro then the games work fine with videos and sound. not crashing on retroarch. If i close retroarch and try again some time it work but most of the time it just crash again till I load the fbneo libretro core and switch back to fb2012 libretro. I try different roms and same problem. I try newest roms but still same problem. I uploaded a video on youtube. please look at it at the beginning of the video it is working but keep watching the video and you will see what I mean Click to see the Video
What video driver are you using? I noticed some weird stuff with your text, which usually indicates a video driver problem. Try going to settings > driver and change the video driver to d3d11 and then close RetroArch and reopen it and see if FBNeo gives you video output then.
I was using gl1 I switched to d3d11 and it is working now. Big thanks. Another thing I also have the similar problem with Nintendo 64 using the Parallel cores. I had changed the video driver to vulkan but retroarch crash every time I open a n64 game. I had tried different video driver but no luck. Any recommendations or any way i can troubleshoot and isolate the problem ?
