If your trackball and spinners are not functioning correctly in MAME on a PC, follow these steps to ensure proper setup:

Step 1: Test Trackball and Spinners

Before configuring MAME, confirm that your trackball and spinners are functioning as a mouse on your PC:

  • Spinner 1 and Spinner 2 should control mouse movement in either the X or Y direction.
  • If this works, proceed to the MAME setup steps.

Step 2: Configure Input Device Options in MAME

  1. Open the MAME emulator on your PC.
  2. Navigate to Configure Options → Input Device Options.
  3. Set all options to Mouse.
  4. Leave Input Providers set to Auto.

Step 3: Enable Multi-Mouse Support

  1. Navigate to Configure Options → Advanced Options.
  2. Under Input Options, turn Multi-Mouse ON.

Step 4: Remap Trackball and Spinner in Each Game

If the trackball or spinner doesn’t work in a specific game by default, it may have auto-mapped to another connected mouse. To remap it:

  1. Launch the game in MAME and press TAB to open the in-game menu.
  2. Navigate to Input (this machine) → Player 1 Controls.
  3. Locate the dial or trackball you wish to remap.
  4. Press Enter, then roll the spinner or trackball you want to assign.
  5. To clear a mapping, press Enter, then ESC.
