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

@BGallagherLA said in Still no light gun support for SMS??:

Also randomly, do you have any idea when Retropie support for Pi 4 will be ready?

There's no deadline and support is on-going, so .. 'when it's ready'.

Thank you @mitu

That worked, I needed to throw in a --disable-x11 too:

CFLAGS="-O2 -march=armv8-a+crc -mtune=cortex-a72 -mfpu=neon-fp-armv8 -mfloat-abi=hard -ftree-vectorize -funsafe-math-optimizations" ./configure --prefix=/opt/retropie/emulators/retroarch --disable-sdl --enable-sdl2 --disable-oss --disable-al --disable-jack --disable-qt --disable-pulse --enable-opengles --disable-videocore --disable-vulkan --disable-wayland --enable-kms --enable-egl --enable-floathard --enable-neon --disable-x11

I may have got rid of the --prefix bit, I can't quite remember now.

Appreciate the help.

Mr Lightgun

How can I ask the devs of the emulators to help with this light Gun trigger mapping functionality?

Update 2:

What a rollercoaster!

So I made some guesses on the joystick ID (above), and got advmame to start long enough to let me map controls. I pulled the trigger, and found it was showing up as j5. I wiggled the gun around, and it showed up as j4. Armed with that knowledge, I went back into advmame-1.4.rc and updated those lines.

Back into duck hunt and... SUCCESS! Sort of. I had movement, and it didn't drift, but it also was clearly moving in 4 directions. Like a joystick.

So I went back to gunconf, set the gun for mouse mode, and went back into AdvMame. Nothing worked (which I expected), but I was able to do that mapping trick and learn that both buttons and movement was showing up as j6. I made the appropriate changes to the rc file, and.. nothing.

Buuuuut, I did learn something about how the rc files works, so I decided to throw caution to the wind and make some changes.

I went back into the rc and set it up this way again:

device_mouse raw device_raw_mousedev[0] /dev/input/mouse0 device_raw_mousedev[1] /dev/input/mouse1 device_raw_mousedev[2] /dev/input/mouse2 device_raw_mousedev[3] /dev/input/mouse3 device_raw_mousetype[0] ps2 device_raw_mousetype[1] ps2 device_raw_mousetype[2] ps2 device_raw_mousetype[3] ps2

I set the lightgun mapping back to "auto", and fired up duckhunt again, and it was a QUALIFIED SUCCESS!

The lightgun is now working (as in, it moves in the right direction at the right time), but there is clearly a calibration and/or sensitivity issue. The gun functions inside a very small area, which I suspect is about the resolution of duckhunt, rather than the resolution of the monitor.

I attempted to calibrate inside of duckhunt, but that's a frustrating experience since the crosshairs bounce all over the place, and I can only guess where I'm supposed to be aiming. Hardly ideal for what I'm trying to make happen here.

I am going to re-calibrate in 4:3 using gunconf, and then play with the sensitivity settings to see if I can get it to match up.

@IntoShadows said in Adding a light gun collection option\button to the showcase theme:

I'm currently using the "Wolfanoz ArcadeOnly 32GB" image

Third party images are not supported here.

I know I’m really late to this party but had to say I too love maddog mccree.

I’m about to build a gun4ir in the next weeks in hopes to have a satisfactory gun for it.

Hi
I wanted to know if the lightgun is compatible with LR-FBNeo
is it possible to have a list of emulators compatible with it present in Retropie? thanks

@BGallagherLA hello do you have a list of the lightgun games for advanced name?

I updated the core and it still doesn't work. Nestopia and AdvMame all work great for me with no calibration/tweaking needed. Just plug and play. Nothing works on Genesis Plus for me, re: light guns.

@mitu Just stumbled over this thread because I am a proud owner of two Aimtrak lightguns since last saturday, and I'm searching for any information about their setup. :)

Following the links from the video's description, I found the github page of the script in question:

https://github.com/Shakz76/Eazy-Hax-RetroPie-Toolkit/

It seems like it modifies an existing Retropie installation and adds some functionality the author deemed to be useful. I didn't dive deeper into it, because I prefer to use Retropie's own tools as long as they get the job done as well.

Getting my Aimtraks to work with any kind of MAME is my next goal, but at present I can't help much further.

@dankcushions I did try with MAME2003plus and Operation thunderbolt and the issue persisted, don't know if other games are fixed.

@mediamogul i havent seen his video

but yes most emulators that use mice work. Dosbox works too for lightgun games

@MrLightgun thanks I just actually updated to the latest version of RetroPie release. I have been holding off because my setup was working great for the most part.

I’m almost done moving my cfgs over and making sure everything is working properly. I believe I will give this process a try and see how it goes.

@caver01
@mediamogul
cancel that, right after a reboot , it works!... I cant thank you guys enough. Awesome Help!

Look for the .rc file at /opt/retropie/configs/mame-advmame

But be careful. Changing the .rc file is tricky and a can result in a failure to boot into advmame.

@illando said in Multiple mice support in RetroArch cores (lightguns, spinners, trackballs):

Not a real fix but I solved pressing "f" and "g" keyboard keys, placing the player2 crosshair in the bottom right corner. :)

Not a real fix, but an incredible simulation. ;)

I can confirm 'Point Blank' refused to launch on AdvanceMAME 3.6 but it works using AdvanceMAME 1.4 core.

Ah, good to know.
