@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

@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

Hi everyone, I have been working and building a collection of emulators that work with Dolphinbar while I await for my Sinden light guns on my Raspberry Pi 4. Anyway, I consider NES and Master System 100% working when using the touch screen setting in RetroArch (lr-fceumm and lr-genesis-gx). MAME 2003 Plus games like Area 51, Space Gun, Egg Adventure, Aliens 3, Jurassic Park work fairly decent. So this leaves me with Genesis, SNES, Dreamcast, and PlayStation. I can get Genesis (Mega Drive) and SNES partially working, however, I am unable to get the second trigger button working - this is the literal show stopper for some games. Has anyone figured this out? As for Dreamcast, I can get the trigger working, but not the mouse/touch feature to move the crosshair. Any suggestions on how to get this working? PSX - for some stupid reason, I cannot get it working at all. I know u/MrLightgun had it working and it should have been implemented by now, but I cannot for the life of me figure it out. I appreciate any help. I feel like my research and experimentation is getting ever so closer to my goal. I appreciate any advice or pointers on these issues, because it's been awesome being able to relive some of the glory days of gaming.

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.

@backstander Never has purple been so perfectly personified.

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.
