MAME help with trackball setup

[jlfreund]

I've got pretty much everything setup and working on my Windows 11 Mame 277 build, except for trackball input. When I run Mame 277 and go to "Input Assignments (General) -> Player 1 Controls -> "Trackball X Analog Inc", I am unable to set it to "Mouse X +" by rolling the trackball.

Here's what I've tried:

• Deleted the Mame/cfg/game.cfg specific configs to avoid any confusion with default config
• Verified mame.ini "mouse" = 1
• Verified mame.ini "trackball_device" = "mouse"
• Verified the trackball is working as a proper HID mouse in Windows, and in the Mame.exe application
• Verified Mame -> Input Device Options -> Trackball Device Assignment = "mouse"
• Verified Mame -> Input Device Options -> Mouse Input Provider = "auto" (have also tried "rawinput")

As a partial workaround, I can see it's possible to set "Trackball X Analog Inc" to "Mouse X+" using my spinner device, but that doesn't help me with the Y axis.

those X and Y analog Inc and Dec are not used by the trackball. they are for trackball games where you would be using a joystick in place of a trackball.  Its best to leave those blank since you are using one. If you were using a joystick it wouyld be whatever keys you have assigned joytstick one to such as left, down, up, right.
