      No. I have been working on a setup that lets me use sights instead of onscreen crosshairs, and had yet to play anything other than the Game A on Duck Hunt just to get the correct angle dialed in.

      But now that I’ve re-read the manual (Duck Hunt),it is clear that the emulator does not function as the normal hardware did.

      Select on the controller centers the crosshairs, and shooting offscreen starts Game A instead of changing selection.

        @mediamogul i havent updated lr-nestopia, but the other reasons were why i stopped using it. The crosshair lag and speed was too much.

          For this specific bug with regard to RetroArch emulator cores I would like to suggest that you all post this information in the libretro forums.

          If you could get this thread going with logs over there I will do what I can to attract some attention from developers familiar with the NES light gun situation.

            That would be great. I do plan on starting a thread there soon, but I'm currently trying to get my thoughts together on the matter. There's a handful of things that need to be addressed to make light gun use more practical in RetroArch and I want to make sure I can present those issues as clearly and concise as possible. I also need to experiment with all the applicable cores to see what issue they might have as well.

              @mediamogul Cool!

              There is at least one libretro dev who takes FCEUmm NES light gun functionality pretty seriously so I think if the details are laid out that is a good place to start.

              For my part there are evidently still irregularities with mame2003 lightgun support. I'm unfortunately not experiencing them myself, so I'm kind of at the same point as you: getting my documentation and description in order before I put out the call for help! :) Maybe this weekend...

                As an aside to anyone looking to change game modes in the mean time, gamepad selection is possible as long as the NES 'Select' button is mapped, or remapped away from the RetroArch hotkey.

                  @mediamogul I just tried the overlays from the rpi-video-manager utility by Floob. I still get this freeze, it happens in all RetroArch cores if there is an overlay active. This is on a stock image from the RetroPie website and 1 overlay added to test.

                  I’m finding it hard to believe this is an isolated incident... I won’t bother you again if you can’t help. Trying to get to the bottom of it. Thanks.

                    We could be on different versions of RetroArch. I haven't updated mine in a little while. I'll update and try again this evening.

                      @mediamogul I appreciate it. I just need a confirmation one way or the other. Sorry to bother you.

                        I just updated everything, installed an overlay and setup the Dolphinbar and everything seems to be working well. I don't know what could be causing the issue. Perhaps a conflict with another mouse?

                            Hello @mediamogul and other lightgun fans: could you answer a slightly remedial question from the libretro side? We know that you have access to the udev input driver -- therefore udev needs to be working well for the retropie lightgun userbase.

                            Are there any other RetroArch input drivers that RetroPie users employ for their mouse-like devices?

                              @mediamogul so strange. I really appreciate you taking the time to test this for me. Another mystery to solve.

                              I do use a keyboard and trackpad combo but removed it from the equation many times. I will revisit that though once again.

                                @mediamogul unless it is the Dolphinbar itself I can not work this out.

                                I need to ask before I purchase a replacement... are you using the regular version of RetroPie and RetroArch? I have updated RetroArch from both binary and source without change.

                                  are you using the regular version of RetroPie and RetroArch?

                                  I am, yes. If it helps, below are the two .cfg files I used for the overlay.

                                  Duck Hunt (World).zip.cfg

                                  input_overlay = "/home/pi/RetroPie/roms/nes/duck_hunt_overlay.cfg"
                                  input_overlay_enable = True
                                  input_overlay_opacity = 0.900000
                                  input_overlay_scale = 1.000000
                                  

                                  duck_hunt_overlay.cfg

                                  overlays = 1
                                  overlay0_overlay = "duck_hunt_overlay.png"
                                  overlay0_rect = "0.0,0.0,1.0,1.0"
                                  overlay0_full_screen = true
                                  overlay0_descs = 0

                                    @mediamogul thanks. I am still having the hard freeze with only a keyboard and mouse with no config changes. Other than adding my overlay. And I’ve tried many. I’ll Jump off this thread but I did start one of my own if anything comes to mind.

                                    I’ll try your configs as well. Thanks again.

                                      No problem. If I think of anything, I'll let you know.

                                        @mediamogul tried your config without success.

                                        Does your Duck Hunt (World).zip.cfg truly point to the nes/roms folder? I don’t normally run per-game configs but I point mine to the opt.../overlays folder...
