Mouse not working in lr-mame2003

grant2258

i have no problems using a mouse or touchpad so i would assume it is ok. I havent tried on retropie though i use RA on my laptop and desktop machine. As long as you set your inndex right us shouldnt be an issue

OliB

Maybe this might helps

under:
opt/retropie/configs/all/
edit
retroarch-core-options.cfg

insert:
mame2003-mame_current_mouse_enable = "enabled"

Also the same line for mame2010 and so on....

[ERROR] [udev] Failed to open device: /dev/input/event1 (Success).

Hi,
I still get the same error:

[ERROR] [udev] Failed to open device: /dev/input/event1 (Success).

I tried the evtest command and I get input when I move either the mouse or the trackball.

I also tried with an old image that I had with RP 4.2 and Retroarch 1.6.7. And the trackball works fine with MAME2003 there. Then I upgraded the Retroarch Version to 1.7.X and it stopped working with the same error.

Seems that there is some kind of problem with the 1.7.x RA with mouses and trackball.
thanks

download retroarch for windows or linux and try your mouse and trackball there. If it still doesnt work its a RA issue else its a retropie issue

there is another user having the exact same issue for NES cores (fceumm and nestopia tested) here: https://retropie.org.uk/forum/topic/20004/mouse-as-a-zapper-lr-fceumm-rpi-3-b/

The error reported [ERROR] [udev] Failed to open device: /dev/input/event1 (Success). is indeed very indicative of a programming bug in RA's input system error handling.
Further debugging is required at RA's level if anyone has the experience/time :) And report back to RA's maintainers.

im betting its permissions not being set right issue this command

 sudo usermod -a -G input `whoami`

reboot and try ( i dont think a reboot is requiredjust on the off chance)

 ls -al /dev/input/

@grant2258 ah good idea! in the other thread I asked the user to check the input devices FILE permissions, and they seemed right.. but didn't think that the current user might not be in the input group. If that is the case then it would be simply a matter of adding the user to the input group. Let's see!

And yes a reboot is not necessary, just re-login the session.

grant2258

i figured saying reboot would be quicker than explaining to a new user to login again either way will work. I didnt even check i just checked my command syntax before posting so I dont know if this is set by default

hhromic

@grant2258 in some older Stretch images I think the input group was forgotten to be set by default, but in recent releases this is corrected and works out of the box. I have installed various stretch images in recent months and they all come with the user correctly configured.

Let's see if the user manages to fix the problem with your suggestion, that would be great news for the other guy on the other thread.

grant2258

well i just checked my standard stretch x64 install the input group isint added there i think this probably is the issue people have been having the good thing is if it is this its so easily fixed on the updated script

hhromic

@grant2258 sorry, I meant Raspbian Stretch for the RPI :)

grant2258

ill install a fresh image rpi and check

hhromic

@grant2258 sure, but no need to install anything, as I said, in recent images it comes correctly configured: https://github.com/RPi-Distro/pi-gen/blob/master/stage2/01-sys-tweaks/01-run.sh#L39

@grant2258 .. but on a second thought, the report said:

thanks

If the user is not in the input group, the older RA should also have failed. Anyway let's wait for the feedback, your suggestion still makes a lot of sense.

grant2258

not necessarily the older ra could have used linuxraw as the input driver. I guess we can just wait for feedback. I would suggest a reboot though as emulation station is already running

hhromic

@grant2258 yes agreed, a reboot would be a definitive approach

@albecacif just to confirm, can you execute groups ? this should show you all the groups the user belongs to. Did you reboot right?

albecacif

pi@retropie:~ $ groups
pi adm dialout cdrom sudo audio video plugdev games users input netdev gpio i2c spi

Yes, I rebooted the system

grant2258

can you the output of

 ls -al /dev/input/by-path/

and

ls -al /dev/input/by-id/
