Core doesn't support multimouse

[jhaleit]

I noticed there's an issue with multimouse support not working. Just wanted to add this here.

You running on a Linux environment too? I'm also not getting it to work even with the udev driver and indices set properly.

@B0RGS just to confirm, are you running the latest RetroArch nightly or building from source?

There are instructions on how to add a PPA that allegedly provides the nightly builds. I can't vouch for this myself: https://www.retroarch.com/index.php?page=linux-instructions

I've been updating it the conventional way via retropie's UI. Not sure what setup script it's using for that. Will look into the instructions you provided though. Hoping to get this resolved before this weekend, but I may be out of luck until retropie updates things on their end.

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

I was able to get this issue resolved using mame2003-plus [https://github.com/libretro/mame2003-plus-libretro/issues/1086]

However, this version of MAME does not appear to support some of the multi mouse games I'd like to play, like pong, and I still can't get mame2016 to respond.

2003-plus apparently automatically binds the mouse bound to a given retropad input to the corresponding player input in MAME. The MAME UI does not indicate any of this so I'm not clear as to what its doing to get it to respond.

Is mame2016 supposed to do the same thing?
