So I was able to make this work by simply unplugging the mouse from the pi, leaving the controller settings in retroarch for fceumm set to auto NOT zapper, and then under settings change zapper mode to mouse.

My wminputA file is as follows:

#IR for mouse REL - fps style
#Plugin.ir_fps.X = REL_X
#Plugin.ir_fps.Y = REL_Y

#ir_ptr
Plugin.ir_ptr.X = ~ABS_X
Plugin.ir_ptr.Y = ~ABS_Y

#custom buttons
Wiimote.A = BTN_RIGHT
Wiimote.B = BTN_LEFT
Wiimote.Up = KEY_UP
Wiimote.Down = KEY_DOWN
Wiimote.Left = KEY_LEFT
Wiimote.Right = KEY_RIGHT
Wiimote.Minus = KEY_ESC
Wiimote.Plus = KEY_ENTER
Wiimote.Home = KEY_LEFTALT

Wiimote.1 = KEY_LEFTCTRL
Wiimote.2 = KEY_SPACE

Nunchuk.C = KEY_C
Nunchuk.Z = KEY_Z

#plugin for nunchuk stick
Plugin.nunchuk_kb.Up = KEY_W
Plugin.nunchuk_kb.Down = KEY_S
Plugin.nunchuk_kb.Left = KEY_A
Plugin.nunchuk_kb.Right = KEY_D

Plugin.led.Led1 = 1

#EOF

#IR for mouse REL - fps style
#Plugin.ir_fps.X = REL_X
#Plugin.ir_fps.Y = REL_Y

works as a mouse in zapper games BUT not even close to as well as

#ir_ptr
Plugin.ir_ptr.X = ~ABS_X
Plugin.ir_ptr.Y = ~ABS_Y

so I'd use the ir_prt not ir_fps mapping.

I've found that if you forget to unplug your mouse before you start the game you can simply unplug it and the wiimote will take over immediately as the mouse.

If using a wireless mouse you must unplug the dongle not just turn the power off to the mouse. This could be problematic for wireless keyboard/mouse combos as you have to unplug the dongle and lose both keyboard and ouse function.

So far I havent been able to get the hot keys to work in game (even thought they work fine in emulationstation) to exit the game and have to use the keyboard for that unless you have a gamepad installed (which doesnt interfere with the wiimote as a mouse as a zapper) then you can use the game pad to exit the game.

@g30ff cheers. I have tried all versions of drivers in the folder with the same output each time.

Appreciate the reply mate.

@dtyler3 What is your version of retropie? Are any other modifications made to it? We need a little more info to help you, and a verbrose log would be very useful too.

@g30ff the drive is just a script that boots a service, but yep tried that ... and also working with Sinden too .. but since this was such a needle, was hoping there was some known mouse issues lingering that could help me pinpoint a resultion

THANKS !!!

@mitu
Will browse a lil bit through the code maybe i can read it out.
Thank you very much for your help :D

@barbudreadmon

Hi barbudreadmon

Also thank you to you for explaining that Virtual Cop for Dreamcast needs a more beefy system

Really appreciate it

Submitted a PR: https://github.com/libretro/RetroArch/pull/11388 .

Should address https://github.com/libretro/flycast/issues/562 and related issues in the X11 version of RetroArch for multiple lightguns.

Closing this now.

toccata10 created this issue in libretro/flycast open multi-mouse broken #562 pjft created this issue in libretro/RetroArch closed Change udev driver for dual lightgun support in X11 #11388

Update: After some tedious testing with the Bare Bones image, I found out that the mouse index in RetroArch isn't the same as the system's. As said before, the Sinden gun appears as /dev/input/mouse0 and /dev/input/event2 in the system. But in RetroArch, I have to set the mouse index to 1!

So far, so irritating. 🙄 Now I can move the cursor in both lr-fceumm and lr-pcsx-rearmed, not only in the Bare Bones image, but also in my own RetroPie system.
😀🍻😁

BUT alas, solving one problem led to the next: The gun seems to assume a higher screen resolution than lr-fceumm and lr-pcsx-rearmed provide, i.e. the crosshair is way too fast and will already have reached the screen border when the gun's real aim just moved approx. a third of that distance. Calibrating the gun by holding lefton its D-Pad for three seconds doesn't fix that, as it aligns the aim at one position, but from there the movement is still too fast.

I couldn't find any reports about this phenomenon on the web. My monitor's native resolution is 1600x1200. Changing the aspect ratio in RetroArch doesn't fix the problem.

Any ideas? Otherwise, my next step will be to contact Sinden support and/or asking on https://www.reddit.com/r/SindenLightgun/. But not today, the lengthy troubleshooting was enough for one day. 😛

@trapexit

Your the Author of the 3DO Emulation for the Pi , well I have to tip my hat to you , o love 3DO and it's a dream to be able to play it running very well on another console ... main reason why I upgraded to a Pi 4

It's ok if you have no idea about the reload situation , whenever you have the extra time , maby a solution will come to mind one day soon ;)

I appreciate your work and really enjoy this Emulation

@arcadez2003

Thank you for informing me

Really appreciate that

I will try it on Mame2003 plus

@Krakatoa If you are interested, I got other systems working too

PS1 games:

SSH into \home\RetroPie-Setup\scriptmodules\libretrocores\

Find lr-pcsx-rearmed.sh

Open it with Notepad ++

Change the section to be like this:
function sources_lr-pcsx-rearmed() {gitPullOrClone "$md_build" github.com/SindenLightgun/pcsx_rearmed.git}

Now go into EmulationStation, or SSH into your box (sudo /home/pi/RetroPie-Setup/retropie_setup.sh)
Go into Options>RPSETUP
Manage packages>Manage main packages>lr-pcsx-rearmed>Remove
Then do an update from source.
Now when you launch PS1 games, go into Quick Menu, then in Options select Pad 1 Type = guncon

When that has finished then you load lr-pcsx-rearmed as your emulator as usual. Then on the menu under options you can change Pad 1 Type to "guncon".

Tested on Elemental Gearbolt, Time Crisis I and II and it works well. However, some games are not working, Die Hard/Die Hard 2, Lethal Enforcers I and II.

For NES,
got into Retroarch Quick Menu
Change Port 1 binds device type to "Zapper"
Map Wiimote buttons same as on Dreamcast example
In Quick Menu, enable "lightgun settings"
then go to Options and change Zapper Mode to "Touchscreen"
save configs and restart

For SNES, similar to NES, but when launching a game, when the splashscreen for NES comes up, press the button on your controller to bring up the launch menu
Change the emulator for the rom to "lr-SNES9x"
When Retroarch loads, go to main menu inputs
Go to Port 2 Binds
Select SuperScope
Map trigger, alt fire like before
In Quick Menu, check lightgun mode "touchscreen"

Master System, same as NES
Port 1 - MS Light Phasrer
In Quick menu turn on show cross hair
touchscreen mode
save game mappings

Megadrive/Genesis:
Set port 2 binds to "MD Menacer"
Same settings elsewhere (i.e. touchscreen)

Still not bad progress!

@FRAQATTAQ said in Light gun does not work for most games:

Guide used: Wagner tech talk

Could you provide a link to the guide, please?

Emulator: emulation station / retropie / mame

Emulation Station and Retropie are not emulators, and Retropie supports a number of different MAME versions. See here for a list. Which one did you try?

The default MAME of the official Retropie image is lr-mame2003 which uses the romset of MAME 0.78. You can see the emulator used (and change it) in the Runcommand Launch Menu.

You'll need the right romset for your MAME version, other romset will probably fail or cause problems. See lArcade and Validating, Rebuilding, and Filtering ROM Collections for more information about that.

Okay, thanks.

I'll wait until the official version of Retropie for the Pi4 is released before I look into more lightgun games. They're less than 5% of my games anyway.

Worth it not to have to worry about a sensor bar. I'm getting them for my arcade, but would also like to use them for my computer. Moving the sensor bar around could cause problems with the wire.

@mitu

Thank you very much for the Link , Very Helpful and Up to date

So a simply answer is It doesn't work Properly at the moment

we're waiting on an update on fixes
