        I have been debugging this, and it is the sdl2.0.5 update that has caused the issue.

        Unfortunately as it is closed source, I am unable to debug it further (at least debugging coolcv), and don't know what in SDL2 would have affected it as other SDL2 apps seem ok. (Changed my mind - I can debug SDL of course)

          Thanks for taking the time to look into this. I've passed the information along to the developer here.

            It's quite likely it's an issue with SDL2.0.5 (SDL 2.0.5 has had heaps of problems on the rpi) - I am going to try and git bisect it, but this will take some time.

            If I find the commit in SDL, I will revert it or backport any fix if there is one. If I can't (and the coolcv author cannot work around it), I may be forced to switch back to SDL2.0.4 again...

              I have found the commit that causes the issue (this references our git mirror, not the original repository)

                Please can you update retropie-setup and update coolcv and let me know if that sorts it (I reverted the problematic commit in sdl2).

                    I'll try to fix fbalpha-libretro's colecovision inputs soon, that way you'll have an alternative to CoolCV.

                        Everything is back up to speed and performing beautifully. It really does amaze me that a problem like this can be zeroed in on among an ocean of possible causes and rectified. Also, I know it doesn't "just happen", so again I thank you for taking the time to do this.

                          @mediamogul , does that mean there is a new CoolCV binary to be had, with these fixes in place? What would be our best way to get it installed over the top of our existing CoolCV?
                          Thanks!

                            There's no new binary, but BuZz fixed the root of the problem and it can be applied by using the 'Update from Binary' option for CoolCV in the RetroPie-Setup.

                              Is anyone else here running a USB sound device with CoolCV? It seems as long as my rpi3 is configured for USB sound, my screen goes blank and becomes unresponsive to any connected keyboard/controllers when I try to play any CV game (even launching a game from command line). I have to SSH in to reboot. This happens with a fresh 4.1 install to the latest 4.1.18 update with sound fix. So far everything else I use RetroPie for is fine.

                                Sounds good, I updated from binary (think I did) and it didnt seem to change, I'm sure Im doing it wrong.

                                For the newbies out here may just give us a quick guide.

                                      I can't speak to the keyboard controls, but you might try adding the following to /opt/retropie/configs/all/runcommand-onstart.sh and see if it solves the screen issue. It was used to solve a similar issue in Kodi a while back and may work here.

                                          I tried as you suggested but it didn't work. I did find out what the problem was. I used the /etc/modprobe.d/alsa-base.conf method of setting the sound device but had to use the /etc/asound.conf method. All seems to be working great now.

                                          Thanks.
