mouse as a Zapper lr-fceumm RPi 3 b+
-
@edmaul69 try to update all packages with kernel on your Rpi3b+, and then replace your core.
-
I tested on a stock updated RetroPie 4.4 and didn't have any problems with either
lr-fceumm
orlr-nestopia
. I plugged in a BT mouse from my pc and it worked without any extra configuration, the pointer showed up on the screen and I could use it (played Duck Hunt). Just to compare, this is the log file from the shooting session - I changed theZapper mode
option tomouse
and applied a shader from the RGUI between rounds. -
@mitu Have you tried using a usb wired mouse? or wireless 2.4Ghz mouse?
-
@sexbeer I forgot to mention, but the mouse has an USB BT Receiver, so it's seen as an USB mouse by the system.
-
@mitu I just tried on a stock updated RetroPie 4.4. and nothing has changed, the problem has not gone. that is my log.
I have an error in this section[INFO] [udev]: Keyboard #0 (/dev/input/event0). [ERROR] [udev] Failed to open device: /dev/input/event2 (Success). [INFO] [udev]: Mouse #0 (/dev/input/mouse0). [INFO] [udev]: Plugged pad: Microsoft X-Box 360 pad (1118:654) on port #0. [INFO] [udev]: Pad #0 (/dev/input/event1) supports force feedback. [INFO] [udev]: Pad #0 (/dev/input/event1) supports 16 force feedback effects.
with all mouses that I have :(
but, I repeat, mouse work in console with cat /dev/input/mice, I mean the system detect it well -
@sexbeer can you install the
evtest
utility (sudo apt-get install evtest
) and test your input devices? This is different thanjstest
as it tests event-based input devices. When runningevtest
it should list all the detected input devices and ask for a number to test. If your mouse appears there, choose the correct number and then you should see all the supported events that your mouse can report. Move the mouse and click buttons and you should see events being triggered. If you don't get to this part, then something is wrong in the udev subsystem for you.It's specially weird that you are gettingAhh just realised that[ERROR] [udev] Failed to open device: /dev/input/event2 (Success)
, which means the function opening the device is not failing but being detected as failing. This would be potentially a bug in RetroArch.mouse0
is actually detected fine, you have another event input device that can't be opened (event2
).Posting the output of
evtest
before asking for which device to test would be useful to understand what input devices your system is recognising. -
@hhromic My system recognizes all devices connected via usb.
evtest
showed that the mouse isevent2
although at the same time it ismouse0
.I think that's because Pad is recognized first and it'sevent0
, then keyboard isevent1
. But It does not matter. Mouse works fine with this test, but not in retroarch -
@sexbeer yes it doesn't matter in which order event devices are detected (gamepad, mouse, keyboard etc). But for me it is weird that retroarch reports and error and the description being "Success". Checking the source code of RetroArch for the error string leads to this:
if (!udev_input_add_device(udev, type, devnode, cb)) RARCH_ERR("[udev] Failed to open device: %s (%s).\n", devnode, strerror(errno));
The
udev_input_add_device
function is returningfalse
but not because of a system error (errno
= 0, which is "success"). Checking further what that function does I found that it checks some things but do not report the actual error, unfortunately, so it's hard to spot what is happening exactly. An alternative would be to add more verbosity and re-compile retroarch.Interestingly, for example I found that it checks if mouse/touchpad devices have absolute coordinates, and fail if the absolute axes min/max are inconsistent:
/* Touchpads report in absolute coords. */ if (type == UDEV_INPUT_TOUCHPAD) { if (ioctl(fd, EVIOCGABS(ABS_X), &absinfo) < 0 || absinfo.minimum >= absinfo.maximum) goto error; device->mouse.x_min = absinfo.minimum; device->mouse.x_max = absinfo.maximum; if (ioctl(fd, EVIOCGABS(ABS_Y), &absinfo) < 0 || absinfo.minimum >= absinfo.maximum) goto error; device->mouse.y_min = absinfo.minimum; device->mouse.y_max = absinfo.maximum; } /* UDEV_INPUT_MOUSE may report in absolute coords too */ else if (type == UDEV_INPUT_MOUSE && ioctl(fd, EVIOCGABS(ABS_X), &absinfo) >= 0) { if (absinfo.minimum >= absinfo.maximum) goto error; device->mouse.x_min = absinfo.minimum; device->mouse.x_max = absinfo.maximum; if (ioctl(fd, EVIOCGABS(ABS_Y), &absinfo) < 0 || absinfo.minimum >= absinfo.maximum) goto error; device->mouse.y_min = absinfo.minimum; device->mouse.y_max = absinfo.maximum; }
Which may be causing the initialisation to return
false
without being a device error itself. You said you tried different types of mice, so I wonder myself what are the odds for all of them to fall in this case.Can you paste the full output of
evtest
while testing your mouse device? in particular the capabilities it shows for your mouse device before testing moving and buttons?I'm sorry of not being able to help you more directly with your problem, but I thought it might shed some light.

@hhromic ok! I connected only one optical mouse and one gamepad. This is log:

@sexbeer ok so your mouse is being detected as relative coordinates type.
Can you paste the output ofls -la /dev/input/
just to confirm device permissions? -
@hhromic after reboot mouse is

@sexbeer Can you try replacing your
nes
system'sretroarch.cfg
file with the default oneinput_remapping_directory = "/opt/retropie/configs/nes/" #include "/opt/retropie/configs/all/retroarch.cfg"
and re-try to see if mouse input works.
-
@mitu all recent tests were on a clean updated image. no system files changed
-
@sexbeer I am intrigued why your gamepad input device files have ACL permissions on them (the
+
next to the permissions in the file listing).It seems you are using an Xbox pad that is using the xpad driver. It might sound dumb but can you try without that pad connected? can you just connect the mouse and a keyboard and see how it goes?

@hhromic It did not help

mouse is

now
interestingly, the mouse works in the terminal via SSH even when the emulator is running -
@sexbeer finally the issue was identified in RA's side.
@grant2258 sent a pull request to RetroArch to fix this issue here: https://github.com/libretro/RetroArch/pull/7730
Once merged your problem should be fixed, keep an eye on that PR @sexbeer ;) -
@sexbeer if you feel like trying the patch from @grant2258 , you can do the following while the PRs are in the process of being reviewed/merged:
cd $HOME/RetroPie-Setup # go to the RetroPie Setup directory sudo ./retropie_packages.sh retroarch clean # clean the build sudo ./retropie_packages.sh retroarch sources # download the sources sudo patch -p1 -d tmp/build/retroarch < <(wget -qO- https://github.com/libretro/RetroArch/pull/7730.diff) # patch retroarch with PR #7730 sudo patch -p1 -d tmp/build/retroarch < <(wget -qO- https://github.com/libretro/RetroArch/pull/7759.diff) # patch retroarch with PR #7759 sudo ./retropie_packages.sh retroarch build # build the patched retroarch sudo ./retropie_packages.sh retroarch install # install the patched retroarch sudo ./retropie_packages.sh retroarch clean # to leave all clean again
Afterwards, just launch your game and test if the mouse is now working for you. In particular check that you are not getting this error anymore:
[ERROR] [udev] Failed to open device: /dev/input/event1 (Success).
Your feedback is highly appreciated! Thanks!
-
@hhromic sudo: ./retropie_packages.sh: command not found
-
type
cd /home/pi/RetroPie-Setup/
then follow the instructions
-
@grant2258 goddammit it works! Hallelujah!
