      @Solid-One thanks for the explanation, that makes a lot more sense.
      I'll mess around with the code in the next few weeks to see if I can add a fixed amount of deadzone to menu/GUI actions only. After all, they are meant to be controlled with the cursor keys; analog input is no advantage here.

        For the in-game issues, I want to report that it's my bad, and has nothing to do with your changes. My ZDoom analog settings were messed up, so it was registering one axis as constantly being pressed. I've fixed that and it seems to be working just fine now. I thought the issues were related because it seemed to be constantly pressing up on both the menu and in-game, but I see that wasn't the case.

        The only issue I have remaining is with the analog on the menu, although I am able to get it to stop registering the analog presses if I move the analog stick around for a while after loading ZDoom. That however only works inconsistently.

        Either way, please disregard my comments about the issues in-game. I did that to myself!

        EDIT: I can consistently get the menu analog issue to stop after it starts by rotating the left analog stick in a circle. That seems to make it stop until the next load of ZDoom.

          @BuZz Any chance this could get merged? It has been an open PR since April.

          Thanks for all your hard work!

            @corezon This will need to be revisited. We are moving to lzdoom and zdoom is being removed (it's already happened on our fkms_rpi4 development branch).

            This is based of https://github.com/drfrag666/gzdoom - branch 3.82

            Our fork was a temporary measure really and was only in place due to bugs with the upstream code (which I believe were possibly caused by fast-math optimisations).

              Did anyone end up looking back into this for lzdoom? Finally got lzdoom and brutal doom going and realised this won't work with it.

                @bassybeats I did. The changes in ZDoom worked with LZDoom with some slight fixes:
                https://github.com/protocultor/gzdoom/commit/8ba7e49184c2be58c0ad03a7602dcd2c4b0ff6fd

                Binaries for Rpi3B+:
                https://github.com/protocultor/gzdoom/releases/latest

                The unfortunate issue is that there's no actual repository for the RPi "version" of LZDoom, since the source to compile comes from a tag; there's not even a branch to work with. So I had to fork the repo and create a branch from that tag to be able to apply the changes.

                If you have to compile it, follow these steps:

                cd ~
                mkdir lzdoom_joy
                cd lzdoom_joy
                # Clone LZDoom from my repo and branch
                git clone https://github.com/protocultor/gzdoom.git --branch joypad_menu --depth 1
                cd gzdoom
                c="$(lscpu -p | grep -v '#' | sort -u -t , -k 2,4 | wc -l)" ; [ "$c" -eq 0 ] && c=1
                # In the following, remove "-DUSE_ARMV8=On" if you're not using a Rpi3 or later model
                cmake -DCMAKE_BUILD_TYPE=Release -DNO_GTK=On -DUSE_ARMV8=On .
                # The following will take A LOT of time
                make -j$c
                # After a long wait... its backup time
                cd /opt/retropie/ports/lzdoom
                sudo mv brightmaps.pk3 brightmaps.pk3.BAK
                sudo mv game_support.pk3 game_support.pk3.BAK
                sudo mv lights.pk3 lights.pk3.BAK
                sudo mv lzdoom.pk3 lzdoom.pk3.BAK
                sudo mv lzdoom lzdoom.BAK
                sudo mv soundfonts/lzdoom.sf2 soundfonts/lzdoom.sf2.BAK
                # ...and finally, replace the installed lzdoom with what you compiled
                sudo cp ~/lzdoom_joy/gzdoom/*.pk3 /opt/retropie/ports/lzdoom/
                sudo cp ~/lzdoom_joy/gzdoom/lzdoom /opt/retropie/ports/lzdoom/
                sudo cp ~/lzdoom_joy/gzdoom/soundfonts/lzdoom.sf2 /opt/retropie/ports/lzdoom/soundfonts/
                

                You still have to do a first-time configuration with the keyboard, at least to increase the deadzone with some gamepads.

                Note that, if you don't have sound, you must create the file .alsoftrc in your home (~) with the following content:

                [alsa]
                mmap = false
                

                (Thanks to @RussellB for the solution to this: https://retropie.org.uk/forum/post/234245)

                EDIT: updated instructions for the recreated branch, which is now based on 3.86a.

                  @Protocultor do we need to have the other version installed to do this? or should be be uninstalled.

                    @ExarKunIv Welp, you end up replacing it, but installing LZDoom from RetroPie-Setup copies scripts to be able to run it through EmulationStation. So, if you're familiar with those you could create one by hand and avoid installing. Otherwise, just do it and replace LZDoom afterwards.

                        I kinda got tired of this being an issue for years in every *nix platform, so I sent a pull request to GZDoom itself:
                        https://github.com/coelckers/gzdoom/pull/1072
                        Let's see if we can see it solved in LZDoom afterwards.

                            Just installed lzdoom on Retropie using the new 4.6 beta.
                            I've got Doom up and running.
                            It works great with an Xbox 360 controller - apart from having to use a keyboard to start a new game.
                            Once in game I remapped all the controls based on the PS1 version of the game.
                            i.e. Strafe left/right is left shoulder/right shoulder
                            Weapon previous/next is left trigger/right trigger etc.

                            Here's a snippet from the [Doom.Bindings] section of my lzdoom.ini file

                            Joy1=+strafe
                            Joy2=+use
                            Joy3=+attack
                            Joy4=+use
                            MWheelUp=weapprev
                            MWheelDown=weapnext
                            MWheelRight=invnext
                            MWheelLeft=invprev
                            DPadUp=togglemap
                            DPadDown=invuse
                            DPadLeft=invprev
                            DPadRight=invnext
                            Pad_Start=menu_main
                            Pad_Back=pause
                            LThumb=crouch
                            LShoulder=weapprev
                            RShoulder=weapnext
                            LTrigger=+altattack
                            RTrigger=+attack
                            Pad_A=+use
                            Pad_Y=+jump
                            Joy5=+moveleft
                            Joy6=+moveright
                            Joy7=togglemap
                            Joy8=menu_main
                            Joy12=invprev
                            Joy13=invnext
                            Axis1Plus=+right
                            Axis1Minus=+left
                            Axis2Plus=+back
                            Axis2Minus=+forward
                            Axis3Plus=weapprev
                            Axis6Plus=weapnext
                            Joy11=centerview
                            Axis5Plus=+lookup
                            Axis5Minus=+lookdown
                            

                            The only thing left is to assign "menu_forward" and "menu_backward" to the Xbox 360 controller. Is this something that's already been done and if so, is there a file(s) I need to replace please?

                            Apologies if this has been asked previously.

                            I was just reading the ZDoom Controls section from here and realised it was out of date.

                              @Protocultor Can you please look into updating this fork of LZDoom for RetroPie? It is currently behind on a lot of updates and bug fixes compared to main LZDoom branch (this fork is v3.84 while the main LZDoom version is v3.86a).

                                @zerosaber75 sorry, but I'm not interested in updates, new features, and the like. My main concern was to make gamepads/joysticks to work with the Rpi and *nix platforms in general, and I've done it. I'm kinda dissappointed that my pull request was completely ignored by the people behind GZDoom, and I've decided not to spend any more time with this.
                                In any case, my fixes are very simple to understand and apply for people interested, if you or anyone else wants to make the latest version of LZDoom work with the RPi. If anyone have any questions about my fixes, I will still gladly answer them.

                                  @Protocultor How can one port the gamepad fixes to the newer versions of LZDoom for themselves?

                                    @zerosaber75 by making these changes :
                                    https://github.com/protocultor/gzdoom/commit/8ba7e49184c2be58c0ad03a7602dcd2c4b0ff6fd
                                    AFAIK some files may have changed directory, but their names and contents remain the same, so by applying these changes you're good to go.
                                    But that's the easy part. The complicated part is what you need to do first, what you were asking me to do: to make the latest (or at least, later) LZDoom compile and run on a RPi, and hoping it will run on a decent speed. Last time I checked, it asked for a sound library that didn't work (for me). That's were I understood why the people in Retropie chose an older tag to publish; it is less messy with the required libraries.

                                      How did you get brutal doom to work with lzdoom, if you don't mind me asking ? Or is there a page you could link with instructions? I swear I've been googling and working on this for hours and I just can't understand what to do. I had brutal doom, sigil, all that working fine on zdoom on the Pi 3, but with lzdoom and the Pi 4 it's just not making sense to me. Thanks in advance for any help you can give.

                                          Hello @RapidEdwin08! I think the ball has rolled all the way, since these changes are now officially part of GZDoom:
                                          https://github.com/coelckers/gzdoom/pull/1163
                                          About the instructions in https://retropie.org.uk/forum/post/216941, I've recreated my branch to mirror the 3.86a tag, and updated some of the instructions to make them work for that tag.
                                          I don't think there is anything else to do now, since it seems even the later LZDoom versions have my changes now, but they appear after the 3.86a tag, which is the last that supports the Pis.
                                          Still, it's good to know that the gamepad will no longer be a problem for *nix users, not even on MacOS. To me, it's a solved issue.
                                          Again, thanks for the initial push of the ball :)

                                            I don't think there is anything else to do now, since it seems even the later LZDoom versions have my changes now, but they appear after the 3.86a tag, which is the last that supports the Pis.

                                            It looks like later LZDoom versions have retained the GL2 compatibility needed for the Pi, so we will update it in RetroPie to the latest 3.87c release. The version should include your code for the gamepad improvements.
