@pinokiooo i'm not an expert (i did this once, long ago, with 2 mouses), but i remember dual pointer devices need udev as retroarch's input driver, and you might also need to set appropriate mouse indexes for each players in retroarch's input settings.

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

Another update, this time with some news about improving the software (mainly for Windows, but Linux was at least mentioned honorably):

https://www.indiegogo.com/projects/the-sinden-lightgun#/updates/all

For the Linux software I have the stability improvements that are overdue for release which I will release this month (hopefully next week) but I will be dedicating some time and effort to the Linux software after the Windows improvements are released. A front end is most definitely required to make things a lot easier to setup and diagnose any issues.

Let's hope that they don't forget (or forgo) the ARM Linux drivers, which I suspect to be second in number of users after Windows, because of the Pi's popularity in the retro gaming community.

@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

@andykt76 great tutorial thank you for doing this. I followed your steps for the PS1 lightgun setup and now I’m stuck on the guncon calibration screen in time crisis. I can’t seem to get it to move past this step, any suggestions or did I take misstep?

Thanks!

@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.
