@Unknown you've been told to stop bumping posts before. please take a day to absorb that message.

After a fair bit of trial and error, just wondering if anyone has any further pointers - could a fullscreen window (rather than just fullscreen) potentially work for this? I'm envisaging the full screen being the size of the widescreen, with the window being 4:3 - potentially the emulator would still register the hit outside of the displayed screen. I'm struggling with the Retroarch GUI options for this though.

@quicksilver I already have, many times. I am talking about the axis, nothing works with the axis

Yes, they do. However you must buy a MayFlash Dolphin Bar. After that, you can use the Wiimote as a lightgun.

@Efriim Thank you! This fixed it. Player 2 is not set up yet as I am waiting for the second dolphinbar to arrive from Amazon which is tomorrow :)

I was somewhat deceptive in my question gathering as I think this is entirely unrelated to the sixaxishelper, as I haven't actually gotten to use the wii controller until now. I have tried removing and syncing the devices from bluetooth config menu and also bluetoothctlthey sync just fine. /proc/bus/input/devices lots of things. Logitech* AnywhereMX & K350 & K400 Sony Playstation(r)3* Controller & Motion Sensors Nintendo Wii Remote* Accelerometer & IR & _Remote & Motion Plus (lists 4 inputs) So my question could have been is the Wii Motion Plus incompatible? I searched the forums but I ignored that they go on and on without answers. It syncs fine, and the jstest buttons respond, it is some mapping overlay, but also there is this Traceback in joy2key. It is very close to working. But very close could be miles, underground. I have a hundred tabs open and a link to this was broken, will go here https://github.com/retropie/retropie-setup/wiki/Wiimote-Controller and hopefully it will work.

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

This actually helped: 1 year ago OK I figured it out. I had to set the hotkeys manually rather than rely on the autoconfig. For anyone else out there with this issue, what you need to do is open the RetroPie menu. Open RetroArch. Go to Settings>Input>Input Hotkey Binds. Go down to Quit RetroArch, and set that to your Start button. Next go down to Enable hotkeys, and set that to your Select button. Go back up to the Main Menu within RetroArch. Open Configurations. Save Current Config. Back out and exit RetroArch. You're good to go now for most emulators. https://www.reddit.com/r/RetroPie/comments/5t44qq/unable_to_exit_emulators_help/

@mediamogul i havent seen his video but yes most emulators that use mice work. Dosbox works too for lightgun games

Yes. I have it set up with a Wiimote and a Dolphinbar. You plug the Dolphinbar into the first USB port (top left), which is the Player 1 slot. Set the DolphinBar to Mode 2 and sync the Wiimote with the Dolphinbar (you have to press the Sync button on both at the same time). That's pretty much it. As for the games, the majority of the gun games I have are arcade games (Lethal Enforcers, Operation Wolf, etc), and just to separate everything from my regular arcade sets (Mame4All, FBA), I put all of my gun games into the Arcade folder, and set the default emulator for every game in that folder to AdvMame 1.4 (If you don't have it on your setup you may have to install it from the RetroPie menu). There is also now support for NES (Duck Hunt, etc), just make sure you have the default emulator for the gun games set to the lr-fceumm emulator, since it won't work in nestopia. Sadly, there is no console support for SMS or Genesis/Megadrive yet, as far as I know. Let me know if you have any other questions.

Well, I don’t know what I did, but the Wiimote suddenly started working... weird...

@markwkidd Thanks Mark.

problem solved, my dolphin bar is broken, only one side is lit.

I solved my concern. In fact it is necessary to modify in the file advmame-1.4.rc the following line: input_map [p2_lightgunx] mouse [2, x] input_map [p2_lightguny] mouse [2, y] Thank you in any case, I could not double cursor on any game.

So it seems to work, thank you. By cons when I change the video for a game, when I restart the game it does not keep the video configuration in time, is this normal? And I have to adjust game by play the touch of my wiimote. Is it possible to make a wiimote button setting that applies to all games and not play by game? should I edit the advmame-1.4.rc?

@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.
