Multi-Mouse support issue on linux

[B0RGS]

Followed the instructions as shown here https://forums.libretro.com/t/configuring-ra-for-multi-mouse-spinners-lightguns-tackballs/12619 , but I'm not getting the results I expected.

What is the expected behavior in MAME once each player’s input binds have been mapped to a proper mouse index?

I expected it to detect the separate mice when I configure the inputs via the MAME UI, but it only seems to detect whatever mouse I’ve bound to player 1 in retroarch. I know that the indices are correct, as I tested each of them on Player 1 and they worked. Input driver is udev as specified.

[ghost]

The only driver that has multi mouse support is udev. If your using wayland its driver is hard coded so you cant change the input driver to udev as is but it can be changed to allow this you would need to request it on the retroarch github page if your using wayland.

[B0RGS]

I'm not familiar with Wayland. Are you suggesting that Ubuntu using it as an input driver and thereby disregarding my retroarch settings where I specified udev?

[ghost]

I dont use ubuntu So i have no idea what the default display server is on it. If its supports both you should be able to toggle between them anyway. enable logging and start retroarch and post the log it created that will let you know if its connecting to a wayland server or not

[B0RGS]

It does not appear to be connecting to a Wayland server and is indeed using udev

[ghost]

Well the good nesws is your are using xorg. The udev drivers are working but they dont log the indexes. This was recently fixed a few days again so you would need to update your retroarch to the latest and it will show your mouse indexes. There was a bug before this update that added mice twice the mouse we needed and a legacy one we didnt. Just co go.good tompile the lastest and youll be good to go

[B0RGS]

Not sure how to update RetroArch to 1.9.6 via retropie (only got me to 1.9.5 where the issue still exists). Will see if I can find a manual way to do it. Guess I'll just have to wait till its available if I can't. Thanks for the advice btw!

[ghost]

no problems at all you change you mouse index in 2s until you fin your mouse 0 2 4 6 ect until you get the update.

[B0RGS]

I'll fiddle with the indices, but I don't think that's the issue. I already know I've got the right ones, because I've tested them individually on player 1. MAME just does not seem to detect them when bound to any of retroarch's other player inputs.

[B0RGS]

I haven't been unplugging anything, so I don't think they would have changed. Or would retroarch itself throw off the indices when I update the inputs?

[ghost]

Well The problem was fixed here https://github.com/libretro/RetroArch/pull/12536 https://github.com/libretro/RetroArch/pull/12557 https://github.com/libretro/RetroArch/pull/11388

best waiting for the official update.

the core itself has a xy device option as well not sure what the default is set to either if your index are right try checking what that option is set too in the quick menu. I dont wanto confuse you here just wait for the updates and see how it goes from there

[mahoneyt944]

1.9.6 was delayed. Should be released officially in the next week or so. The retroarch webpage has more details.

[mahoneyt944]

1.9.6 is now available

[B0RGS]

Still no dice here. don't know if it was coincidental, but after I installed 1.9.6, all my indices changed. I tried to remap my inputs in accordance with the event# as I did before, but that wasn't working anymore, so I tried the mouse# instead.

When doing that, I tested all the relevant indices on player 1's input binds and each device was detected in MAME as Mouse 1 as before, but MAME still won't detect any of them when bound to the other player input's.

I can get it to detect multiple mice inputs if I use the new feature where you can redirect input binds to another player, but that doesn't solve my problem. I want to play games like pong using two spinners which both use a mouse X-axis, so I need MAME to actually see them as separate mice. They'll all show as "Mouse 1" doing it this way

[ghost]

what game are you using ill try go through this with you.

[B0RGS]

I'd appreciate that! Lets try Blasteroids. Its a 2 player / multi dial game where I'm trying to use two spinners.

[ghost]

Ok i have managed to get it working no issues. here is what to do.

quickmenu core options set xy device to mouse

Now go to settings -> input->port1 controls-> mouse index set it to spinner player 1 device number Now go to settings -> input->port2 controls-> mouse index set it to spinner player 2 device number

[ghost]

you can also test with midres and ikari for dial games tested with blstroid.zip above

[B0RGS]

I already had XY set to mouse. Were you not using legacy controls? Maybe that's where the issue was; I had been trying to map everything in MAME's UI. Detection seems to work when I disable it.

[ghost]

I only use legacy controls. The dial is automatically mapped to mouse. You cant map it in the ui even in the original mame2003. What mame does is let you use other inputs but the mouse will always over ride for dial games if it has data from the mouse. as long as your ports are set your good to go.

ps. Sorry i never seen your question about indexing yes it has changed /dev/mouse[n] was removed this is a legacy ps2 for compatibility. I also added the device friendly names to the index for people with multiple mice the old way had no logging sorry if it caused you issues the changes where needed.

[B0RGS]

So you're saying that I should not have expected to see any response in the MAME UI when I tried to map the Dials to the spinner? It will just work automatically? I was assuming it would have said Mouse1 X and Mouse2 X etc. in accordance with the retropad number.

[ghost]

later mame versions do this and suport half axis this particular version doesnt its hard codes mouse to player even in the original mame078 the ui wont responde to mouse movement. That why you have have to set the mouse device like you do a retropad as there all set to the same value for mouse though 0 default. Its worth noting you would have to set these ports even if it did work as all player mouse devices will point to the same device unless changed

[B0RGS]

I see. I'll have to see if I can get this working in later versions of MAME, but as far as 2003-plus, this appears resolved. Thank you for your help!

[ghost]

no problems at all
