Trackball / Spinner support for BigBox - Spin the wheel!

📋 Summary

Add support for trackballs and spinners to control Big Box wheels, using up and down mouse style movement to navigate game and platform selection.

❗ Problem

Big Box wheels are typically controlled via keyboard, gamepad, or joystick, but many arcade setups include a trackball or spinner that feels perfect for this type of navigation.

Currently:

• Trackball and spinner movement does not map cleanly to wheel navigation

• Arcade cabinet users lose an intuitive, tactile way to browse

• This has been requested multiple times over the years, and similar front ends already support it

💡 Proposal

Allow trackball and spinner input to control wheel scrolling:

• Map up and down movement to wheel navigation speed and direction

• Support both trackballs and spinners as mouse movement style input

• Add an input option in Big Box controls, for example:

  • Enable Trackball or Spinner Wheel Control

  • Sensitivity or acceleration setting

  • Optional inertia smoothing for a natural spin feel

📦 Benefits

• Makes arcade cabinet navigation more authentic and fun

• Improves accessibility for setups that are built around these controls

• Reduces reliance on a separate joystick or d pad for browsing

• Brings Big Box closer to the experience offered by other arcade focused front ends
