@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.

@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.

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

@escc1986 said in Lightgun Question : How To Use Duel Wiimotes with Dolphenbar ?:

My Question is Could you use 2 Dolphen bars and use 2 wiimotes to play 2 player ligh gun games on the pi4 ... if so does any one know how to do it ?

I've never tried (I only have one bar) but I think that's how it is supposed to work. I suppose you use the bar in mode 2? This mode only supports one connected Wiimote. :(

or Could you use 2 wii motes on 1 bar ?

This would work in mode 4, right? This mode is used for the dolphin emulator, and I think it doesn't work with Retropie without proper drivers.

There is a link I found recently, where someone made a high-precision Wiimote "driver" that works with 4 IR LEDs around the TV set. I suppose that this works a little like the Sinden Gun, but I have not come around to try this. Maybe if you have the time and dedication you could try this. Maybe it even works with multipe Wiimotes, I don't know?!

Theory : im thinking but not certain , but maby i can have/enable duel mouse then it could work possibly ... but how do you enable duel mouse on retroarch on pi4 ?
for mame2003 games

As I said, I have never tried this. Maybe you can in a fist step try getting it to work with one Dolphin Bar (in mode 2) and a regular mouse?

@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!

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.

@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 :)

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

@markwkidd Thanks Mark.

Here are some news regarding the subject, it's only for psx for the time being :)

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

Anybody tried Blue Shark (really old school ;-) ) with Dolphinbar/Wii controller ?
Does it use crosshair ?
It's supposed to work both in lr-mame 2003 and 2010.

The SNES ones also allow for a mouse, I think you need to set it up in the controls tab though. I've used it for Mario Paint.

@cloudd I ran the code on this page and i got the mayflash dolphinbar
working on the latest fedora 36 desktop, super happy playing super mario galaxy with dolphin emulator installed from fedora software center

@Febbweiss

Hi , Anyway I can contact you in a private message or email

You seem to have got something working that I was having an issue with , hope your able to help me

Thank you

i have a hunch about the issue, but i can't confirm it. i've logged it with retroarch here:
https://github.com/libretro/RetroArch/issues/4333

and maybe i'll buy a wiimote and sensor bar to test myself. do you know if a generic chinese wiimote will still work on the pi? i guess if they work on a wii they should be understood by the linux driver?

dankcushions created this issue in libretro/RetroArch closed Allow a device to be both a Gamepad AND mouse (eg, Wiimote, PS4 DualShock 4) #4333
