Multiple mice support in RetroArch cores (lightguns, spinners, trackballs)

kneli

Can lr-nestopia handle the Wiimote and Dolphinbar already? I read through this page on GitHub but couldn't make out if it was working or not?

Yes, I have used that combination in Windows (not relevant to you probably) as well as in Ubuntu (relevant). You need to make sure that you are using the RetoArch udev input driver, you need to have the NES header database in the right location(can't recall the filename while mobile right now), and I believe you also need to set a core option in Nestopia.

Maybe if you test this the both of us can get the exact process written up for the Nestopia core docs so that it's more straightforward in the future.

@markwkidd Sorry to get a bit off topic and call you out here, but I posted a while back on a similar but not exactly fitting topic that nobody was able to answer, and it seems you're the person to ask.

Can lr-nestopia handle an NES Power Pad input? From what I've seen it can't (at least on the Linux version), but maybe I'm missing something.

I don't know anything about this specifically, but it seems like standalone Nestopia supports the Power Pad. The libretro core is a pretty shalllow fork, almost completely caught up with current Nestopia on github: https://github.com/libretro/nestopia

If you're sure it works in standalone Nestopia I'd suggest posting in the libretro forums and/or creating and issue in the libretro Nestopia github repository. I'm not sure which one of those places is more likely to get a response on your issue.

I did some testing yesterday and it didn't work right away, I think only the trigger worked. I'm running lr-nestopia on RetroPie. I'll do some research on the udev input driver and the NES header database you mentioned and try to get it working. I will document the process if I get it to work and post it both here and in reddit.com/r/retropie. (Y)

@kneli the file you need is NstDatabase.xml and you can find the official Nestopia file at this location: https://github.com/rdanbrook/nestopia/blob/master/NstDatabase.xml

@markwkidd I'm not really familiar with Linux. I ran the command sudo usermod -a -G input 'whoami' which didn't return any errors. Is this correct? Do I need to install the udev or the libudev and libxkbdcommon packages?

Hi guys,
I tried to read all the tread, but I'm not able to have a crear vision about how the things are going with NES and MASTER SYSTEM light gun emulation.
Could somebody make a recap about the current status of light gun emulation support using lr-nestopia and lr-genesis-plus-gx cores with Dolphin Bar please?
After some tests I can say only AdvanceMAME cores is working perfectly using Dolphin Bar. Using lr-nestopia I can only play with mouse but not with Dolphin Bar.

Info about my configuration are:
Pi Model 3
RetroPie Version 4.3.2
Pre made SD Image on RetroPie website
Dolphin Bar

@illando I've played Duck Hunt for NES and Rambo III for lr-picodrive (?) successfully.

illando

@hooperre Using what Dolphinbar setting mode 1,2,3 or 4?
I'm using #2 and the trigger and other buttons on the Wii Remote are working, but I can't move the cursor from the center of the screen.
Same behaviour for all the cores, lr-nestopia excluded where I can play with the regular mouse.

What other settings should I check?

@illando Apologies. I'm using an air mouse not a dolphin bar. I missed that in your last post. I think it should still be similar with the dolphin bar with an x,y mouse. Sorry, I don't have a dolphin bar to check.

They generally use a different kind of positioning. Air mice normally use relative positioning and the Dolphinbar, as well as high-end USB light guns use absolute positioning. From what I've heard, now that absolute positioning and pointer devices have been ironed out in RetroArch, success still depends of support from the individual cores. It could be that Nestopia needs to be developed further to accommodate.

illando

@mediamogul Thanks or the clarification.
Recently Openemu (that is using a Nestopia 1.42 core) is perfectly capable to work with dolphinbar connected to my MAC.
The actual Nestopia I'm testing on Retropie is 1.49, so maybe it's depending from an integration by Retroarch.
Am I wrong?

I looked at this a little this evening and was unable to get it to work myself. I switched ports, mouse indexes, input drivers and core options in both lr-nestopia and lr-fceumm. I ultimately ran out of time to experiment, so there may still be a certain combination of all the factors that'll work, but I was unable to find it.

illando

@mediamogul It seems that Retroarch dev team recently added "absolute" mouse support.
https://github.com/libretro/RetroArch/pull/5512
After updating Retroarch on my retropie, lr-nestopia core is working perfectly with dolphinbar (mode 2).

Talking about Master System there are still some problems with lr-genesis-plus-gx core, and the game crash, but the developer are working on it:

@illando Does Update All Packages in RetroPie grab that new feature of Retroarch that you have listed?

illando

@hurricanefan Maybe. I prefer to update separately and and using the "from binary" option.
These are the actual versions of RetroArch and cores I'm using and that I can confirm are working perfectly using DolphinBar (mode 2)

RetroArch v. 1.6.9
lr-nestopia v. 1.49-WIP
lr-genesis-plus-gx v. 1.7.4

About the Genesis-Plus bug "crash with MS Light Phaser control and Crosshairs option enabled" I found a way to solve it, and sometimes is working, sometimes it crash, I need time to find a correct procedure to avoid the bug!

illando

Is there a way to get mouse support on PlayStation?

mediamogul

@illando

Not currently with RetroArch, but there's a light gun plugin that's likely to be compatible with pcsx-rearmed

Edit: On a second look, it appears to be Win32 only.

illando

@mediamogul Thanks!

Considering this topic is about "Multiple mice support in RetroArch cores". Do you know if there's a way to hide the second and unused light gun crosshair? In some AdvanceMame games it keep stands in the center of the screen.
