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?
Now go into EmulationStation, or SSH into your box (sudo /home/pi/RetroPie-Setup/retropie_setup.sh)
Go into Options>RPSETUP
Manage packages>Manage main packages>lr-pcsx-rearmed>Remove
Then do an update from source.
Now when you launch PS1 games, go into Quick Menu, then in Options select Pad 1 Type = guncon
When that has finished then you load lr-pcsx-rearmed as your emulator as usual. Then on the menu under options you can change Pad 1 Type to "guncon".
Tested on Elemental Gearbolt, Time Crisis I and II and it works well. However, some games are not working, Die Hard/Die Hard 2, Lethal Enforcers I and II.
got into Retroarch Quick Menu
Change Port 1 binds device type to "Zapper"
Map Wiimote buttons same as on Dreamcast example
In Quick Menu, enable "lightgun settings"
then go to Options and change Zapper Mode to "Touchscreen"
save configs and restart
For SNES, similar to NES, but when launching a game, when the splashscreen for NES comes up, press the button on your controller to bring up the launch menu
Change the emulator for the rom to "lr-SNES9x"
When Retroarch loads, go to main menu inputs
Go to Port 2 Binds
Map trigger, alt fire like before
In Quick Menu, check lightgun mode "touchscreen"
Master System, same as NES
Port 1 - MS Light Phasrer
In Quick menu turn on show cross hair
save game mappings
Set port 2 binds to "MD Menacer"
Same settings elsewhere (i.e. touchscreen)
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.
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?
