      @BGallagherLA I don't know what version of RetroPie you are using with your brother, but this is simply not true for latest RetroPie with 1.8.8 RetroArch. It has been tested and confirmed that without this workaround it does not work even if you have manually loaded the right core and rom, and even if the two RetroPies are on the same lan. Also I don't think that the distance is particularly relevant.

        @saccublenda I'm using RetroPie 4.6. Not sure what version of RetroArch but whatever version 4.6 came with I guess. I have myself set up as the Host as you set up in the RetroPie menu on the Pi. I start a game, hit a button to bring up that menu where you can choose emulators and whatnot. From there I scroll to Launch with Netplay enabled and then tell my brother it's up. He goes to the RetroArch Netplay lobby and finds me and connects to my game and it works great.

        There are games that don't work and such, but we've gotten it to work regularly.

          But like I said, I think the key is to make sure you have a port forwarded/open on your router if you are hosting and it will work.

            @BGallagherLA When using Netplay from a PC, I usually activate the option to use a Relay server. For some reason, games stutter less and you don't need to open ports. Have you tried that in RetroPie?

              @BGallagherLA The problem is related to using RetroPie as guest, not as host.

                @saccublenda Ohh. I see. I guess that would make sense then. My brother usually plays through RetroArch on his PC or his phone. We tried to get my other brother to play through his Pi and it never worked.

                  @saccublenda Thank you soooooooo much for that workaround. It worked for me and my brother. Linked up all my configs for the emulators we will be using. Can't express how thankful I am.

                    @strohseph You should thank @mitu since he found out this workaround, I am just reporting it.

                        @strohseph strohseph Hello! Sorry to ask such a basic question, but how and where should I paste these shortcuts? I read @saccublenda post, but don't know how to to create them - I'm no good with console stuff and generally only mess around with settings via the Retropie and Retroarch UIs. Is there an idiots step by step of how to add these? Thanks so much, Mark.

                          @mpnuttall As explained in my post, the command ln -s will create the symbolic link. For example
                          ln -s /opt/retropie/libretrocores/lr-fceumm/fceumm_libretro.so $HOME/.config/retroarch/cores
                          will create a symbolic link to the file /opt/retropie/libretrocores/lr-fceumm/fceumm_libretro.so in the directory $HOME/.config/retroarch/cores.

                            @saccublenda Thanks very much for the reply. So do I just paste all of that in to the console (if that's even what it's called!) in, say, Putty? And also do everything in the very first post of this thread of course, I assume? Thanks again.

                              @mpnuttall Yes, you have to paste this command in the terminal. The commands in the OP are essentially the same in my post, with the exception of the relay server, which I think is not needed if you have open ports on your router.

                                @saccublenda Brilliant, thank you. My friend has been having 'port mapping failed' issues (as well as the 'failed to initilise Netplay' one which seems to be what this thread is trying to address) so will try with the relay I think. This is all very new to me - tried hosting earlier to see what happened (with relay on) and it told me I had connected to Nick!! No idea what I'm doing really 🤣

                                  I did the copy and paste from your entire list for the libretro cores.

                                  It's kind of making a confusing mess of all things.

                                  Is there a simple way to remove all of those symlinks?

                                  I can use either PuTTy or WinSCP.
