[Solved] Trackball not working after 4.3 update

dankcushions

@majin-wamu that's great! thanks for the explanation as i've never personally used this new functionality :D

@caver01, i think this will work for you. I'm not sure about the share x/y setting - i guess it should work once you have the spinner assigned to player 1 (or whatever).

i guess if you'd previously used different mouse devices (trackball for centipede, spinner for blasteroids, etc) for player 1 in multiple games (thanks to the previous 'every mouse is player 1!' issue), you will now have to set up cfg overrides for each game, setting the right mouse device as player 1.

@dankcushions Since this is a new option, should we add some instruction to the wiki? I am assuming it is the community who updates the wiki, or is it is a select group?

yeah! well, anyone can edit the wiki - updates welcome!

@caver01 wrote an excellent trackball/spinner guide here: https://github.com/RetroPie/RetroPie-Setup/wiki/Spinners-and-Trackballs - I think this is where new instructions should go (?)

@caver01 I just started on on a new section for the RetroPie docs about multi-mouse configuration. Does what I have written here match your experience? https://github.com/RetroPie/RetroPie-Setup/wiki/Spinners,-Trackballs,-Lightguns,-and-other-Mouse-Devices#configuring-retroarch-emulators-for-multi-mouse-use

I gotta say, assuming I can get this working (it sounds like @Majin-Wamu has it working) this is actually GREAT NEWS! It means we can, with minor configuration effort, setup a matrix of mouse inputs. There will be plenty of questions and feedback from users, but the net result is a lot more flexibility.

I am definitely OK with individual overrides, since my indices would have to change from ROM to ROM. This is perfect, actually, as I like having direct control over the setting. Since I do see the mouse devices in my log file, the only question I have is: what exactly to I add to my .cfg file? I am imagining it is something like player_x_mouse_index = or something like that.

@markwkidd Great write-up and addition to my trackballs/spinners wiki. The only addition I would include is whatever the answer is to my question above.

@caver01 Below is the relevant section of my retroarch.cfg. I will add something like this to the wiki.

input_device_p1 = "0"
input_player1_joypad_index = "0"
input_libretro_device_p1 = "1"
input_player1_analog_dpad_mode = "0"
input_player1_mouse_index = "0"
input_device_p2 = "0"
input_player2_joypad_index = "1"
input_libretro_device_p2 = "2"
input_player2_analog_dpad_mode = "0"
input_player2_mouse_index = "1"
input_device_p3 = "0"
input_player3_joypad_index = "2"
input_libretro_device_p3 = "1"
input_player3_analog_dpad_mode = "0"
input_player3_mouse_index = "2"
input_device_p4 = "0"
input_player4_joypad_index = "3"
input_libretro_device_p4 = "1"
input_player4_analog_dpad_mode = "0"
input_player4_mouse_index = "3"
input_device_p5 = "0"
input_player5_joypad_index = "4"
input_libretro_device_p5 = "1"
input_player5_analog_dpad_mode = "0"
input_player5_mouse_index = "4"
input_device_p6 = "0"
input_player6_joypad_index = "5"
input_libretro_device_p6 = "1"
input_player6_analog_dpad_mode = "0"
input_player6_mouse_index = "5"

@markwkidd Excellent. SO, I will add some lines to a per-rom config--for example, I will need to setup acameltry.zip.cfg to force the change to another mouse index so it looks at my spinner interface instead of the trackball for that ROM

I am very curious now about how the Split X/Y core option will affect something like Blasteroids which was working great the old way. @dankcushions alludes to this above, but I will test with a similar blstroid.zip.cfg, as this title will also need to use the same index as Cameltry. Obviously, there will be others.

One statement that will have to be made in the wiki is that the indices might be different for each of us. Case in point, @Majin-Wamu's trackball was failing, while mine was working--something I attribute to index order of the mouse devices. It's probably not random, but with all of the hardware possibilities in the world, there's no way to predict how one build will behave with respect to the actual controls. In other words, there is nothing that would connect Index 1 to a trackball--it's all mouse inputs and your index order may differ from mine.

I allude to that somewhat in the wiki as it applies to AdvanceMAME. It has been a while since I read through it, but there might be language in that section that we can use to emphasize this nuance.

Thanks for this pointer -- I just found the language you mentioned, tweaked it a little bit, then slotted it into the wiki.

@markwkidd Looks good. There will need to be some re-writing of what I originally put in there for lr-mame2003, but we need to test the outcome of the Split X/Y core option. I can do that tonight, as I have hardware use case where my spinners are not on the automatically mapped index (plan to make that config adjustment on ROMs that need it) and I definitely use the Split X/Y.

It might be nice to keep the lr-mame2003 section as an example of a libretro core that will use the index details above, but to include an updated description of Split X/Y, depending on how/if it still works. <EDIT> I mean to say--I know it still works, as I was using it in Blasteroids (albeit with a trackball!) but I mean, if it works when you push mouse input to another index.

@caver01 I was pretty excited to finally get it working. Now my single trackball works for both player one and two! I knew there had to be a fix somewhere because my thought was since at least one your mouse inputs was working, mine must be able to work somehow too. Sorry if it seemed like I was going in circles earlier on, but I was trying to figure things out.
Thank you for all your help!

caver01

@majin-wamu Heck, if it wasn't for you, I might not have noticed the same issues for a lot longer. I am really happy with the outcome, as this is how I imagined it might one day work in Retroarch emulators. I still need to setup my configs and test them, but your success is promising.

Majin Wamu

@caver01 Thank you. That is nice of you to say. I will try to get involved with these forums and github and help others if I can. I don't get involved enough online which is a bad thing for a software engineer. The only forum I have been involved with is Open Pandora, not sure if you heard of them. Another open source linux based project.

caver01

I am happy to report that during the past couple of hours I went through the ROMs I have loaded on my setup and I was able to make custom configs for those that used the spinners. They all work great, even the ones that split X/Y between players with that core option. Games like Blasteroids, or Super Sprint, Off the Wall (Sente) all work fine now. Thanks so much for the details, and especially, for the update. This is actually better than before I think.

Majin Wamu

@caver01 Yeah! I bet that is pretty awesome to have that option. Now each player can have their own trackball or spinner. Something I kind of wanted to do for a future arcade I build.

caver01

@caver01 Well, I tried updating the brief lr-mame2003 section of the wiki page I created and for some reason github flagged my account! Does that happen to everyone? oh well. I had a few corrections to make, but perhaps some one in support will get me sorted soon.

Yeah, now we can all build that 3-trackball Rampart cabinet and forego AdvanceMAME.

Majin Wamu

@caver01 The only issue I have is it would be expensive. Unless there is somewhere else we can go to get a good trackball for cheap, the one I got was around $100 or so; but I must say, it works really well. Much better than others I have played at arcades which sometimes seem to only move under a lot of force.
The trackball on your roadcase looks beautiful though.

markwkidd

One other update which was merged into RetroArch yesterday also allows for modern lightguns like Wiimote/Dolphinbar (tested) and Aimtrak (not yet tested).

For my next personal project, the holy grail has been multiple light guns in Lakka with mame2003 which is within reach :D (Now I need to start getting serious about a cabinet...)

I don't own this trackball myself, but there are a lot of them out in the world: https://shop.xgaming.com/collections/arcade-parts/products/x-arcade-trackball-assembly-usb

That's a great price for a full-sized heavy-duty 3" trackball that looks to be (and reviews confirm) a very good option for arcade cabinets. It is almost have the price of my U-Trak. The one thing the U-Trak has going for it is that it stands very proud in its shell making it a lot easier to flush mount without carriage bolt heads showing.

In some respects, I kinda wish I had opted for a smaller trackball, but the 2.25 versions tend to be even pricier.
