I found a problem and it is now solved. I ran lr-dosbox-pure in verbose mode and in log /dev/shm/runcommand.log I found error:

eglCreateImageKHR: failed to create image for buffer

After searching for a while on the Internet, I found a tip for editing the file /boot/config.txt and add the line:

gpu_mem = 256

After this the display no longer flashes (flickering) and everything works fine.

I still have to figure out how to emulate a mouse like a touchpad...

@mitu It's honestly just a super basic, no frills, nothing special keyboard. I did also think about that whole mouse index and wonder if it was maybe giving priority to the keyboard, but then I actually did a test with a simple Dell wired keyboard and it did the same thing. It was seriously weird af.

Here's the keyboard I am using:

I'm not familiar with Pegasus, but I don't think that it's limited to 'command line' , it should work in the desktop env. It may need a configuration file to start ?

@mitu sorry for doubting you, I think you were right after all. I downgraded to 1.9.5 and things are working great now!

Looking forward to retropie upgrading when possible! I like to try to stay on the official latest branch when I can.

I'm no expert, but I think RetroArch can only have one mouse index per player. So I don't think you can assign two of these devices at the same time through the menu. If it were possible to somehow make the operating system see two input devices on the same device index that would be one way. I have no idea how to do it though.

I think as painful as it may be, the only thing to do is assign whichever device the most games use as the default and then create game specific overrides for those that use the other device type.

@retropieuser555
At last I have located this menu and I have managed to make the appropriate changes so that the mouse recognizes me.

If it were not for your help, I would not have achieved it. Thanks ;)

Okay, I hadn't noticed that setting before, don't know how I missed that. Only problem is I'm dealing with a spinner on one particular machine, so I don't have mouse buttons (left/right click). Switching to this setting disables the joystick and buttons meaning I lose almost all functionality.

Is there a way I can create a remap file that assigns button0 and button1 on my arcade controller as left and right click. Maybe also enable two other buttons (or even the joystick) to act as mouse up/down (y-axis +/-)?

@mitu Thank You

@mitu The original pastebin link is still up above your reply, but the newest logs show no mouse activity, even though I was spinning that thing like crazy :
This is the whole log...

@mitu I used the first option to add those binds to the retroarch.cfg file in the snes folder and I have all my SuperScope games working just fine now. Thank you!

@mitu holy cow, it actually worked. Them guys are really quick, seeing how I installed the emu only last week.

Thanks :)

@tpr not in mame2003, however mame2003-plus just added official support for the middle mouse click. 😎😃 You can update or install it from source to get the new input.

@dankcushions

Can you forgive me little rant earlier? Sorry. I've had a good play with it now and I think it's working. And I understand what you mean by pressing the hotkey and F1. Is there a way to have it by pressing F1 alone?

I've Reset Retroarch config and plugged in a Wired Mouse and keyboard and OP Wolf is working now.

I've also changed my RetoArch to Ozone just like my PC. It's much less confusing now. It's going to take some time to get used to this :)

Submitted a PR: https://github.com/libretro/RetroArch/pull/11388 .

Should address https://github.com/libretro/flycast/issues/562 and related issues in the X11 version of RetroArch for multiple lightguns.

Closing this now.

toccata10 created this issue in libretro/flycast open multi-mouse broken #562 pjft created this issue in libretro/RetroArch closed Change udev driver for dual lightgun support in X11 #11388

Works a treat! Thank you so much.

lr-opera worked on Lemmings with Player 1 as the mouse, it didn't occur to me to try Player 2 for Sega CD.

from the Retropie setup menu in EmulationStation enable Runcommand option

select a game to play ... press a button to enter the Runcommand menu and select a lower resolution for the Video Mode than you're currently running the game at.

Ah, so you're thinking of capturing the mouse up/down movements and sending them to ES as joystick movements. ES wouldn't know the difference. Not bad. My set-up isn't wired to pull this off, but it's definitely an idea.

I currently use my trackball as a mouse in PIXEL. It'd be nice to scroll through ES with my trackball, but alas support is not included.
