      Ive scoured the google this afternoon, and havent found a solution. Im hoping I am being really silly and overlooking something.

      I recently got the GRS USB Yoke. It is detected perfectly, but it appears that Mame has a very nasty dead zone which makes it pretty much unusable for Star Wars. The cursor basically goes from 0 to 100% immediately as Mame just ignores every thing through the deadzone.

      Tried on: Advance Mame, Mame2010, and Mame2003

      I found the below topic [1] that seemed similar, but tracing through it I had no luck either.

      The steps I have attempted up to now:

      • Following the steps in the Universal Analog Calibration [2] I added the joystick as a xboxdrv. The issue from there, Mame just still seems to want to use the original device, or at least it seems. Regardless deadzone persists
      sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \
    --evdev /dev/input/by-id/usb-Baolian_industry_Co.__Ltd._BL_flight_yoke_#1_8D6D17A65548-event-joystick \
    --silent \
    --detach-kernel-driver \
    --force-feedback \
    --deadzone-trigger 1% \
    --deadzone 1% \
    --mimic-xpad \
    --evdev-absmap ABS_X=x1,ABS_Y=y1 \
    --evdev-keymap BTN_TRIGGER=a,BTN_THUMB=b,BTN_THUMB2=x,BTN_TOP=y \
    --ui-axismap x2=void,y2=void,lt=void,rt=void \
    --ui-buttonmap lb=void,rb=void,tl=void,tr=void,guide=void,back=void,start=void \
    &
      • I then found an article stating that if you remove the read permissions from the original device, that it should use the xboxdrv. I confirmed that before I add the xboxdrv, the original device is no longer detected in Mame (good). After adding the xboxdrv back in, same results. deadzone persists.
      sudo chmod g-rw /dev/input/js1
sudo chmod g-rw /dev/input/event2

      Any ideas? Maybe I just completely overlooked the how to disable/config deadzone directly in any of the Mames. Every reference to it indicated that in Windows/mame.ini there is a setting. I could not find that same reference to RetroPie. Is there something Im doing with the xboxdrv that is not allowing it to honor the reduced deadzone?

      Any help is appreciated. Just want to slay some tie fighters today -- but wound up in rabbit holes. Thanks - Ice

        @icebear81 mame2003 doesn't support true analog. I would recommend using mame2003-plus then you can adjust the deadzone in the core options in retroarch. Then under the mame menu -> analog controls (menu within the emulator), you can adjust the sensitivity per game. Make sure the game is set to use the controller you wish . You set this under "input this game"

          Nice -- just found mame2003-plus under experimental. Working on the install now. This is exciting!

            @mahoneyt944 Thanks for the help. Installed Mame2003-plus. From the game, I went into Retroarch QuickMenu and adjusted the deadzone from 20 -> 5.

            From there I tried Star Wars without the xboxdrv .. target still goes from center to edge in one quick jump. I then added the device as a xboxdrv (below). Going back to Star Wars, the original controller was no longer registered - this is good, as prior, this was never the case.

            I configured the Input for this game and it found a new device (RP4 over RP3 previously). Good news so far, as something at least is different.

            From there, tried the controller, and still center to edge as it just seems to think the deadzone is there. I looked at the Analog Controls and Y was at 70% sensitivity and X 50% ... Adjusting those didn't seem to affect anything.

            Any other thoughts -- I thought this may have worked ... Really appreciate your assist here.

              sudo /opt/retropie/supplementary/xboxdrv/bin/xboxdrv \

              at command prompt try

              evdev-joystick --l

              if you see your yoke listed, try

              evdev-joystick --s /dev/input/event*

              where * is the number of your controller (eg event0). If you see a figure for flatness, thats the deadzone. You can set it to zero with this:

              evdev-joystick --e /dev/input/event* --d 0

              see if you can get that far.

                      @wstanek thanks for the tips .. but that didnt seem to make any difference.
                      I ran it for the xboxdrv, tested, and then killed xboxdrv and re-ran/tested

                      ## xboxdrv then test
evdev-joystick --e /dev/input/event9 --d 0

## raw controller
evdev-joystick --e /dev/input/event2 --d 0

                      maybe I missed something ?

                        @icebear81 Try going through all the events, I'm not sure that event9 is the right one.

                        I used Advmame and had the deadzone problem. I'm trying to find my notes and the guy who helped me solve it.

                          @wstanek Thanks!

                          event4 is the raw yoke (this was earlier event2 but this changes during reboot as devices come online)

                          I: Bus=0003 Vendor=32be Product=1402 Version=0111

                          now there is also event5 which is when the GRS Yoke is enabled in mouse mode

                          event9 is when I grab the raw event as an xboxdrv

                          Your Xbox/Xbox360 controller should now be available as:
  /dev/input/js4
  /dev/input/event9

                          I could very well me muxing something up --

                            Quick update, maybe this will give more info ...

                            After doing the above, when I add the xboxdrv device as the input in Star Wars, it now associates as R4 HAT

                            Looking at the event details, that has a -1,0, 1 range .. so .. if anyone knows how to disable Mame from grabbing that device over the ABS_X and ABS_Y

                                Event code 0 (ABS_X)
      Value      0
      Min   -32768
      Max    32767
      Fuzz      16
    Event code 1 (ABS_Y)
      Value      0
      Min   -32768
      Max    32767
      Fuzz      16

                                Event code 16 (ABS_HAT0X)
      Value      0
      Min       -1
      Max        1

                            Again, at this point, Im not sure if Im supposed to be using the xboxdrv or the raw device -- thanks for the assist

                              I have the exact same problem, any direction is all or nothing.
                              I assumed the yoke has been seen as a digital device rather than analogue?

                                @robbiedog Yeah ... the more I dig into this, the more I think you are correct that its seeing the controller as digital and not analog -- and its not actually a deadzone issue.

                                        @icebear81 This might sound obvious, but did you try contacting GRS? I'm sure they have extensive experience setting up their product in mame.

                                          @mahoneyt944 he does a lot of video's with Wagner's tech talk, the yoke/Pi setup video is "coming soon", I'm not sure if icebear contacted him (email is on the back page of the manual), but I was waiting for that. I might email him...
