Multiple mice support in RetroArch cores (lightguns, spinners, trackballs)

markwkidd

@hurricanefan You're right that until now only AdvanceMAME has had this support but times are changing. This is new RetroArch functionality that, for at least a little while, is Windows-MAME 2003 only (so no RetroPie until casdevel gets time to add that support).

I have only been using Area 51 and Terminator 2 but this should work for all lightgun games in MAME 2003 --- if not, it would be appropriate to report as a bug. Theoretically 'absolute coordinate' support for lightgun emulation will not just for RetroArch's MAME emulator cores either.

@markwkidd I look forward to when this works out of the box on raspberry pi. :)

lightgun games are controllable by a single mouse in mame2003 already, just not multiple mice (as is my understanding).

i'm sure i tested a single mouse on mame2003. it definitely works for all the trackball games etc.

@dankcushions multiple mice work in RetroArch with the udev driver, I'm pretty sure. I think I have verified this myself, but there has been a lot of mouse input testing in my life lately so I guess there is a chance I could be misremembering.

Frustratingly, the "flatpak" install method for Ubuntu gives me every input driver except udev, and I'm having an issue compiling RA from source right now too. Once I get properly setup for Linux testing again I will keep moving forward.

@markwkidd Hmm... My Area 51 doesn't work with lr-MAME 2003. Is that area51.zip you're using? Hope my last message didn't come off as ungrateful. I was just surprised because I don't recall getting mine to work. Must have a mismatched ROM.

Yes, I'm running area51.zip with the matching CHD in a subfolder folder that is named area51. If you're on rPi hardware it should at least run, even if very slowly.

Hi @dankcushions I'm having no trouble with multiple simultaneous mice via the udev input driver in Ubuntu 17.04.

If you're tracking the 'absolute coordinates' github Issue you probably know that udev support for Wiimote/Dolphinbar is also getting closer and closer. :D

Edit: casdevel's new input debugging libretro core is pretty handy in case anyone else wants to see exactly how their mouse/lightgun/etc report input to RetroArch: https://github.com/casdevel/input-debugger-libretro

Right now there are barely any instructions, but if you ever try it out the most important thing to know is that you have to use the RetroArch F1/Quick Menu to get into the Core options once you first start it up.

markwkidd

Hi folks -- these features are now polished up a part of RetroArch's udev input driver. Support for absolute devices like Dolphinbar/Wiimote should just work. Woohoo!

There is a new section of the spinners and trackballs doc devoted to 'multi-mouse' and how to configure it: https://github.com/RetroPie/RetroPie-Setup/wiki/Spinners,-Trackballs,-Lightguns,-and-other-Mouse-Devices#configuring-retroarch-emulators-for-multi-mouse-use

Hi, I'm trying to apply this in order to hace two trackballs for marble madness or three wheels for súper sprint, but I'm too dumb and can't for my life get it working.

Could somebody put here some detailed instructions please? I will thank.

Have you tried these instructions? https://github.com/RetroPie/RetroPie-Setup/wiki/Spinners,-Trackballs,-Lightguns,-and-other-Mouse-Devices#configuring-retroarch-emulators-for-multi-mouse-use

If you have, where in the process did you run into problems?

@markwkidd
I know the mouse indexes with the cat order, I verified that the input driver in retroarch is udev and I set one of he mouse indexes for each player, but no results.

What am I doing wrong or what am I missing?

I should have asked earlier: which emulator core?

@markwkidd
lr-mame2003

@markwkidd
lr-mame2003

I will be honest I have not experienced this combination of symptoms so far.

Can you attach a keyboard and confirm that it is functional in lr-mame2003?

Also, is it possible for you to copy your logs to a service like pastebin and post the link?

edit: A few more ideas.

Does mame2003 work in other respects -- ie with a gamepad?

Do you have any other input driver options than udev? If so, they probably don't support multi-mouse but it could be a clue to know whether other input drivers recognize your mouse devices at all.

@markwkidd
As far as I can tell now:

Keyboard works fine.
Three Mouses are seen by the pi, using the cat order symbols appear when moving them.

Now I have no access to the pi, but this night I will try with the joypad and with other drivers different from udev.

Finally I have no idea on how to put the --verbose option.

Many thanks for taking your time helping me.

you select it via the runcommand - https://retropie.org.uk/docs/Runcommand/

'launch with verbose logging' or something like that. then after exit, the log is in /dev/shm/runcommand.log

@dankcushions
Ok, I will try it too. Thanks!

I have added this information to the docs, thanks!

Can anyone help me with this? Im trying to play term2 on lr-mame2003 with usb mouse. Retroarch and mame are updated. Raspi sees mouse with cat /dev/input/mice. Verbose logging says event0 for mouse. Set in retroarch accordingly.

Now the trouble:
Im unable to calibrate the lightgun. I cant set mousebutton as button 1 in retroarch input or in mame configuration screen (tab). I cant do anything with the mouse.

Ps. Mouse works fine in uae and quake3. Read the docs several times, and tried everything that i can think of.
